Ditching Patullo as OC was obligatory, but it may not solve the problem with the offense. I think the problem is that this season's offense is the offense that Sirianni wants. Patullo is his man and his man closely followed Sirianni's preferences. Sirianni likes a timid offense, because he believes that minimizes turnovers. He also wants a very simple offense, probably for the same reason. Even in his interviews, he doesn't really address the need to make the O more unpredictable or to scheme new ways to get the receivers open. We have two all-pro cornerbacks, yet almost every game the other teams receivers are more open than ours. Usually not the guys covered by our two young all0pros (kthis last game was an unfortunately timed exception -- SF clearly schemed a few pass plays to beat them and it worked), but other pass defenders. We've had a good pass game at points in the season but, apart from Goedert, it often relied upon Smith and Brown to make highly contested catches (one problem on Sunday, I think, was that Brown seemed injured on one of his first half drops.). Sirianni also wants to lean very heavily on running plays and Patullo liked runs right up the middle).
Sirianni's favored approach worked last season, because the offensive line had a monstrous season and Saquon had fresher legs and wasn't being targeted as heavily. I was stunned that the Eagles didn't scheme new wrinkles for this critical game. With the same QB and the same top 5 receivers, they should have been able to add more complexity to the pass schemes, compared to last season.
From this year's media coverage, iit seems like Brown wasn't the only guy on offense who wasn't happy with the very predictable plays and their sequencing.
There was all too much "we just need to execute better: comments from Sirianni this year, with far too little actual adjustment to the offensive strategy and tactics.
