May mean something, may mean nothing, but last year Bills had 7 LBers in TC, only 4 that were not viewed as special teams only in Edmunds, Milano, Dodson, and Bernard. Mata, Andre Smith, and Spector.
This year they have 8, but Milano, Bernard, Klein, Williams and Dodson are all high on the LB depth chart. They still have Spector, Mata, and Howard who are all roster worthy players.
I still feel we see more 3 LB sets, they have the players for it.
