I think it is hard to judge Hogan with NE and compare it to what he may have done In Buffalo, for a few reasons:
1. Pats have a lot more talent in the WR/TE and RB (catching the ball) than the bills so he is going see fewer targets because of it.
2. Brady is as many pointed out one of the GOAT and will make people look better.
3. IMO a damn amazing O Coordinator scheming plays that work best against an opponent.
