The Packers achieved their goal of getting to the bye week without a loss in the record books. As has often been the case this season, though, it was far from a flawless performance across the board. 

Here are the five biggest takeaways from the Packers’ 27-20 win.

1. Philip Rivers’ arm must be sore

Rivers threw the ball 65 times on Sunday. That’s more passing attempts than Aaron Rodgers had in his past two games combined.

Rivers was everything that Mike McCarthy thought he was going to be. With pre-snap adjustments, quick releases and accurate throws, Rivers nearly willed San Diego to a victory.

There were several records set by Rivers in this game. His 43 completions are the second-most in NFL history, with Rivers also setting franchise records in attempts and passing yards.

2. Strange day for Packers defense

That discussion leads to Green Bay’s defense, which allowed Rivers to mostly have his way throughout the game. Not a single pass was intercepted, though the Packers did have seven passes defensed and put 13 quarterback hits on Rivers.

Most importantly, when Green Bay needed a stop the most, rookie cornerback Damarious Randall rose to the occasion and batted away what would’ve been a game-tying touchdown in the final seconds.

Still, allowing 503 passing yards makes it difficult for defensive coordinator Dom Capers to give too glowing of an assessment to his group. It was "bend, don’t break" taken to the extreme. It’s also fair to wonder how the second half would’ve been different had Chargers wide receiver Keenan Allen not left in the third quarter with a hip injury. Up until that point in the game, Allen already had 14 catches for 157 yards on 15 targets.

The Packers made San Diego’s offense one-dimensional by forcing rookie running back Melvin Gordon to fumble twice in the first half. That, along with a seemingly minor Gordon injury, sidelined the former Badger for the rest of the game.  But the Chargers also made themselves one-dimensional.

Breaking down the tape of the game should be an interesting challenge for Capers. The pros are obvious, but the cons are just as apparent.

3. Jeff Janis: leading receiver?

Green Bay didn’t have a single receiver with three or more catches. Rodgers’ 16 completions were to nine different players.

With 79 receiving yards, it was Janis who found himself atop the team’s final box-score statistics. The second-year receiver had a 46-yard catch and a 33-yard reception, translating his preseason success to the regular season for the first time in his career.

Ty Montgomery’s injury midway through the game added him to a growing list that already had Jordy Nelson and Davante Adams sidelined. That opened the door for Janis, who did well in making the most of his opportunities.

Randall Cobb had a dropped pass when he was wide open, and no other receiver played particularly well either.

It sure seemed unlikely when the regular season began that Janis would ever lead the team in receiving yards in any game, especially in a non-blowout situation. Now the question becomes whether Janis will be part of the game plan when the Packers return from their bye week. Adams should be back by then, and Montgomery’s status is to be determined, so Janis waits to find out whether his performance earned him more snaps this season.

4. Eddie Lacy’s ankle injury and role

Surprisingly, James Starks was Green Bay’s starting running back in this game. Starks got the ball on the first offensive play and ran for 25 yards.

Lacy has been battling an ankle injury, but it seemed like he had been making positive progress in recent weeks. To see Lacy finish with three yards on four carries must have more to do with his health than with Starks’ positive performance.

Over the past two games, Lacy has 30 rushing yards on 17 carries. He hasn’t scored a touchdown since Week 1. Lacy’s ankle injury has clearly affected his ability to get on the field and to be productive when he does get the ball.

5. Perfect time for a bye

Usually an undefeated team on a six-game winning streak would want to keep going uninterrupted. That is certainly not the case for this year’s Packers.

Green Bay entered Week 6 with 11 players on its injury report, and that doesn’t even include Nelson and linebacker Sam Barrington, both of whom are on injured reserve. Lacy has been bothered by his ankle, B.J. Raji missed the Chargers game with a groin injury and Morgan Burnett has played in only one game this season with a recurring calf injury. James Jones has an injured hamstring, and fellow receiver Adams hasn’t even reached 100 yards yet this season due to an ankle injury. Now, Montgomery waits to find out the severity of his injury.

The Packers’ next two games are against the also-undefeated Denver Broncos and Carolina Panthers, with both games away from Lambeau Field. With an injury report this lengthy, Green Bay can count itself fortunate that a week off happens to fall at this point in October.
