No, actually it is looking very goood.
Diggs and his sulking, non-productive ways are out of the locker room. The Bills went on a 5 game winning streak to win the division title in spite of Diggs lack of production.
Diggs had 37 catches for 349 yards and 1 TD in the last 8 games of the regular season, while being on the field for 80 plus percent of the offensive snaps.
Bye, Stefon. Those stats and better can be replaced quite easily, minus the attitude.
