Julian Edelman's a top-10 WR. Mohamed Sanu was on pace for 100 catches in Atlanta and played an important role in making Matt Ryan MVP a couple years ago. Ben Watson played a meaningful role on a team that should have gone to the Super Bowl last season. N'Keal Harry was a 1st round pick. James White is the best receiving back in the league. Guys like Edelman and White are taken for granted by Patriots fans.
These aren't scrubs. Could they use an Antonio Brown? Sure. But it's not purely the supporting cast. Josh Allen has outplayed Brady with Cole Beasley, John Brown, and Frank Gore's rotting corpse.
