I'll say it again: Both teams knew the game was meaningless and that a round 3 was likely. Siriano outright said it to McCarthy in front of the camera. Both sides were just playing base, vanilla schemes on offense and defense. That favors offense.
The next game isn't going to look like that. You will see far more blitz packages, disguised coverages, etc. This goes for both teams.
When the score of the next game isn't 40-34, don't ask "what happened to the offense?!?!?"
Eh this take doesn’t make sense to me due to plenty of evidence of the contrary.
First of all, in the sporadic criticism of the eagles defense all year, the one thing people have pointed to is their lack of exotic coverages. They kinda play what they play and don’t do to much razzle dazzle naturally. This has been true all season, not just the Dallas game. Chris Simms talks about this a lot. Unless they decide to try something completely new or they’ve been saving their real scheme for the divisional round of the playoffs, what we saw is generally how they play.
Secondly, you can tell by the wide open Devonte Smith touchdown on 4th down that they weren’t dialing it back offensively other than the QB run. Collinsworth discussed this in real time. All year the eagles have been running a pick play to the tight end coming across the formation on that play. This game they decided to throw a wrinkle in and have Smith fake the rub and pop up field. Diggs reacted to what he’s seen on film all year and charged the TE. This allowed Minshew to find a wide open Smith all alone in the endzone. Again, Collinsworth noted that this was a new wrinkle that they added.
Based on those two pieces of evidence specifically, I don’t see how you could say they threw in the towel schematically. Not even going to touch the strangeness of claiming two NFL coaches in week 15 both decided to play vanilla football in the expectation to see eachother 4 weeks later. Not super logical but you got it.
