2. The LA Chargers have superior coaching
Yes, the play-calling left a lot to be desired last Sunday. Head coach Brandon Staley looked like he was playing not to lose instead of playing to win, and it was stagnating for his offense.
But LA still has the edge in coaching when it comes to this competition. The Eagles head coach, Nick Sirianni, has had significantly more impactful failures for his team. Sirianni has not successfully managed his personnel this season. Though they finally ran against Detroit and earned a solid win, Sirianni has consistently shelved his own run game while opting to instead put all the pressure on Jalen Hurts--who doesn't do very well under pressure.
Staley, in tandem with Joe Lombardi, has a much better record of effectively harnessing the talent on his offense to produce big plays. Outside of this recent timidness, LA's head coach has trusted the talents of Herbert and Co. to capitalize on aggressive play-calling on taking big chunks out of the field. He's designed an offense that works to their own strengths in a way that Sirianni hasn't done with his own team.
When it comes to the defensive side of the ball, Staley has also started to turn around LA's embarrassing run-stopping inability. The unit looked much better against New England on Sunday, and continued improvement in that area is going to be key in getting a win against the Eagles. Staley is doing exactly what coaches need to do in identifying and developing weaknesses throughout the season.
Even if Staley has regressed in his offensive approach as of late, he's still proven that he can rally his team to victory. This is likely going to be a tight game, and having a coach that players trust to win is a huge asset in the Chargers' favor.
