Arguably no athlete in history has captured the unending interest and imagination of Wisconsin sports fans the way Brett Favre did during his time in Green Bay.

The Packers’ Hall of Fame quarterback had a unique, exciting, freewheeling, chance-taking and polarizing style of play that helped him win a Super Bowl and set numerous NFL passing records. And he had a one-of-a-kind personality off the field, at once larger-than-life but immediately relatable – real, raw, charismatic and endearing, but also tormented and certainly not without vice.

In his new book, "Gunslinger: The Remarkable, Improbable, Iconic Life of Brett Favre," best-selling author Jeff Pearlman examines it all – good, bad, ugly and other – in a fascinating biography that tells the story of No. 4 for the first time. Though Favre himself declined to be interviewed, Pearlman spoke with 500 sources from the quarterback’s life for the nearly 400-page book.

On Tuesday at 6:30 p.m., Pearlman will be at the Elm Grove Library, 13600 Juneau Blvd., to speak and read from his book, which is already making waves among local and national sports fans. Before his appearance in Wisconsin, we spoke with Pearlman to discuss the process of writing the book, why he wrote it and what he learned that surprised him, the expectation of backlash and Aaron Rodgers’ high-profile repudiation of one anecdote and just what made the captivating and polarizing Favre so popular.

OnMilwaukee: When you do something of this scope, talking to 500 people and writing a 400-page book, what do you personally come away with? You've covered sports for a long time, knew some of the people involved and probably had some preconceived notions, but what do you come away with that you're most surprised about, intrigued by or you learned that you didn't know going in?

Jeff Pearlman: The thing about doing a book is you start with this base knowledge and then you learn everything. It's actually a funny question that you get asked a lot when you promote a book which is, what did you learn that surprised you? And it's almost like, what did I learn that didn't surprise me? The reason you call so many people is you get all these stories behind the stories, and you find out things that you never knew, like ... I can name a million different ones.

I didn't know that Brett Favre knew all the words to "Rapper's Delight." I didn't know that Brett Favre missed his sophomore year of high school because of mono. I didn't know that Brett Favre, when he was little, made his little brother drink a concoction of his own pee and mud. I didn't know the relationship with his mother. I didn't know the details of his father's life.

There's so many things you learn about them. That's the whole reason ... I never understand someone who does a biography and interviews 20 people. It doesn't make sense. The whole fun isn't digging through the clips; I mean there's some satisfaction to that. The fun is finding all these unique ... finding the priest who was with Favre right after his father died and is kneeling by his side. That stuff is amazing. Talking to the people who were there right after his car accident when he almost died and can tell you what it was like and what they were thinking at the time, and seeing Brett lying there and not knowing if he's going to live or die. That's kind of why I do it all. That's what I enjoy about it at least.

In this genre, books about iconic athletes and teams, fans often already know the good things – the on-field accomplishments, and with Favre, his toughness and larger-than-life persona. Do you think it's inevitable the new stuff that comes up seems to be more negative, digging up things subjects don't want dug up, like Favre's demons?

I don't actually, but I think what happens is, like ... so you end up doing some excerpts, or the publishing company will hand out a list of points from the book, and it's never going to be like – and I'm not blaming the publishing company; I mean, it's business, it's marketing – but it's rarely going to be like, "Hear about the time Brett Favre had an amazing game against whoever!"

Like, the excerpt in Bleacher Report was a Rodgers-Favre relationship. They requested that. The excerpt in Sport Illustrated was about Favre's year getting drunk in Atlanta. But I think people who read the books ... When I read really good biographies, I don't stop and think 'Wow, that's really great.' If you read a really good book, it's just all enjoyable, you're taking it all in. Then, hopefully you're good enough (as a writer) that you can put someone sort of – it sounds corny – but on the field with him when he's entering the game, his first college game. Like, he entered his first college game and on the sidelines he threw up Schlitz. He drank a case and a half of Schlitz. To me, that's the kind of detail I freaking love. Right?

And it's not going to generate headlines, it's not going to have people saying, "Hey, how dare you write this?" But that's almost the point. You read it and a book should be a pretty seamless – it should be so seamless that the stuff you learn that's new, that's worthwhile, people don't even … they don't stop to think about because it's just a seamless thing. Like, "Oh my God, I'm reading about this game. This game is amazing. Holy cow. Hey Betty, did you know that Brett Favre's first game, he threw up Schlitz on the sidelines?"

I’m not sure if that makes sense but like, it’s not all negative. It's actually all these details cobbled together to be a narrative, and most of them are actually positive and exciting and enlightening, but the ones we tend to notice the most are the negative, I agree with that.

When you finish your manuscripts, but before the book really starts circulating with people, do you already expect criticism and steel yourself against it? Green Bay can be pretty provincial, and Packers fans are very protective of their sports heroes; do you prepare for some backlash?

I do. I hate it. I always hate it. I hate it. That's my least favorite part of the whole experience because these books are exhausting. Also, the other thing is you're relying a lot on memories of people for a lot of these experiences. You really are. That's a fact. I wish everything were documented – although I don't because then you wouldn't have anything new – but you are relying on the memories of people.

You interview someone ...  I'll give you the perfect example. I'm going to have to talk about; I’ll talk to you about it: the whole Aaron Rodgers and Brett Favre. The "good morning, Grandpa." You've heard about this, right?

Yes, I was definitely going to ask you about that (Rodgers has refuted an anecdote in Pearlman’s book that he called Favre "Grandpa" on the first day of Packers organized team activities).

Yeah, I didn't even talk about it that much, but I'm so prepared, I know I'm going to get asked about it a hundred times. To me, you should always just be as honest and upfront as humanly possible. I was told by about a gazillion people to interview Craig Nall, who is a great guy and he was the backup quarterback that year, a couple years that he was there, and he was awesome and there wasn't one thing he told me that did not check out. He was great. He told me the story of Favre and Rodgers.

As soon as this thing came out, I went back and looked at my transcript of my interview with Craig, and it was clear: It was the first day, blah, blah, blah, the first time they met, blah, blah, blah, then this all comes out, and I'm like, I have the transcript, I know this is verified. I know he hated being called Grandpa – that I got verified. I know he didn't feel good about Rodgers. All that's there, and I have the timing from Craig Nall, who was one of his closest friends on the team. But it comes out, and then Craig kind of reaches out to me – I don't know exactly how it happened; I think it was a DM on Twitter – and says it wasn't their first meeting in OTAs, it was their first meeting in training camp.

And like, here's what kills me about that. I'm being serious about it. Everything about that story actually still holds up. Aaron Rodgers reports to training camp, it's his first day of training camp, he walks in the cafeteria, he says, "Good morning, Grandpa," Favre is incredulous that this guy would say that.

It's all there. I just happen to have it on the wrong date. I had it a month earlier than it actually happened, and all of a sudden it allows people to be like, "Well, how could you get that wrong?" Even though I reported it really well and, like, it actually pains me because I know how much time I put into this. I know Rodgers, he said it. He knows he said it. But he's able to cast doubt on it because I had the wrong date. So, that sucks.

And I beat myself up over this sh*t. I truly do. And I thought about this one a lot because I asked myself, like, were I an editor, what would I say to the writer? I honestly would say that is almost as inconsequential a mistake as you could make. The context is still there, it was said and "blah, blah, blah." But it still is the first excerpt on Bleacher Report and it's sort of how the book was introduced to the country.

What can you do? I don't know. Does it undermine the book? I hope not. If it does and some people decide not to read it, there's not really much I can do about it.

The main thing is, I feel like my track record ... I'm not saying I'm David Halberstam. But I do think after seven books, my track record on reporting, it kind of speaks for itself. My track record is strong, you know? I think it's strong. I'm not a guy who gets sued for books. I'm not a guy who has had an issue with any apologies. I'd say my track record is strong, and something like this comes along, especially in a town that is as rightly, understandably provincial about their football team, it makes it kind of ... it can be harsh. But you make a mistake, that's a problem.

What do you hope these types of deep-dive books – like this and the Walter Payton and Showtime Lakers ones – really accomplish? Not only for sports fans and the subjects, but also for you as a writer?

That's a good question. I mean, I think the goal when you write biographies is that no one else wants to do one after you. You hope that someone, maybe four years from now, 10 years from now, or even 20 years from now goes, "You should write a book about Favre." "Eh, Pearlman did that book in 2016, we don’t need it." You know, Walter Payton. I love books by, like, Mark Kriegel, who wrote this awesome Joe Namath biography, or Jonathan Eig on Lou Gehrig, Leigh Montville on John Williams. I read those books and I honestly think to myself, "I would never touch those subjects. I don't know what else I could do with them." You want that, you want people to just be entertained, you want them to learn.

But I don't have, like, and grand thoughts on legacy or anything. I just love writing books. I love researching. I love doing it, so it's really a joy for me. So if someone gets enjoyment out of it, that's cool, and if it adds a little bit of historical context to these figures, that's good too.

If Favre had played in a different town, a bigger media market than Green Bay, do you think you would even have a book to write because all this stuff would have already been out there and documented?

No, I think if he had stayed in Atlanta, just as an example, I think he’s Johnny Manziel or Todd Marinovich. I don’t think it even takes off. I think he needed to go to a place like Green Bay.

You mean the talent doesn’t take off? Or his problems are worse or more covered?

No, I mean I think he would have drank himself out of football probably. I think it was something about Green Bay that was like ... and also being with (Mike) Holmgren, that was the perfect coach for him. Being with that staff, with like (Jon) Gruden, (Steve) Mariucci, Andy Reid.

They knew how to use his talent and kind of nurture it. It would have been very easy for a coach to get Brett Favre and not really know what to do with him. He wasn't a great listener. He threw into double coverage, sort of a free-for-all kind of quarterback. He's the kind of quarterback who gets a lot of coaches fired early in his career.

With Favre’ style of play and his persona – for better and for worse and everything in between – why was he so beloved in Green Bay and so popular nationally with fans and media? Especially when it comes to his vices and some of the things he struggled with and personal-life exploits, and the interceptions and coachability – even with all that negative stuff, people loved the guy. Why do you think that was?

I was thinking a lot about that after last year's Super Bowl when Peyton Manning kept namedropping Budweiser. Remember that? It was so tacky and cheesy and corporate. I feel like that's the kind of thing Favre never did. He wasn't corporate, he wasn't tacky, he wasn't cheesy. He felt very real. And half the people in Wisconsin have Favre stories to tell, whether it's him drinking or him hanging out after the games, signing autographs and all of that. He was great with kids.

I just think his realness really resonated with people. When he sucked, he manned up and owned it. When he was great, he never shoved it in people's faces. He talked a funny style of trash. He was known for farting, which sounds gross but it’s so human. Even, like, the addiction to Vicodin, the drinking. He just was this really flawed ... I feel like, so I covered A-Rod (former Yankees star Alex Rodriguez) a fair amount in baseball when I was with Sports Illustrated. He was actually the anti-Favre. He was like, everything was perfect, every answer was manicured. Everything had to be at a perfect right angle, and no one ever really took to him in that way, with love and inspiration. He was just a great baseball player.

I think Favre – Favre was like a wrinkled sweatshirt. He was just this guy, and he was kind of dirty and scrappy and sometimes he was great, sometimes he was terrible, but he kind of felt like one of you.

Born in Milwaukee but a product of Shorewood High School (go ‘Hounds!) and Northwestern University (go ‘Cats!), Jimmy never knew the schoolboy bliss of cheering for a winning football, basketball or baseball team. So he ditched being a fan in order to cover sports professionally - occasionally objectively, always passionately. He's lived in Chicago, New York and Dallas, but now resides again in his beloved Brew City and is an ardent attacker of the notorious Milwaukee Inferiority Complex.

After interning at print publications like Birds and Blooms (official motto: "America's #1 backyard birding and gardening magazine!"), Sports Illustrated (unofficial motto: "Subscribe and save up to 90% off the cover price!") and The Dallas Morning News (a newspaper!), Jimmy worked for web outlets like CBSSports.com, where he was a Packers beat reporter, and FOX Sports Wisconsin, where he managed digital content. He's a proponent and frequent user of em dashes, parenthetical asides, descriptive appositives and, really, anything that makes his sentences longer and more needlessly complex.

Jimmy appreciates references to late '90s Brewers and Bucks players and is the curator of the unofficial John Jaha Hall of Fame. He also enjoys running, biking and soccer, but isn't too annoying about them. He writes about sports - both mainstream and unconventional - and non-sports, including history, music, food, art and even golf (just kidding!), and welcomes reader suggestions for off-the-beaten-path story ideas.
