I don't think the lousy passing game can be explained entirely by bad receivers. It just looks terrible by design. I also think the running game is more on Kromer, decent O-line talent, and Cook and that the play calling is just awful regardless of whether or not he is directed to prioritize ball control or ground game or whatever.
But I absolutely agree that McDermott is a strong influence here. And it's a bad one. I know the Jets game was scrubs playing scrubs, but it looked like completely different play calling and the TE game, which was never particularly limited by talent, looked more open than ever. Even the WRs made some plays, thought that could simply be a terrible secondary. Anyway, I thought during the game that it really looked like Brady was given some leeway and it was much better in obvious ways.
