Per the ESPN Scouting on Thomas:
"Thomas is a young, developing linebacker who is best suited in a Tampa 2 system based on his size and athletic skills. He is a versatile player who can play both inside and outside. He has been a productive special teams player in the past."
If he is the starting OLB then I don't like the move but hopefully he is a depth/special teams guy, which I am guessing is the reason they signed him.
I am starting to get a feeling that the bills may go LB in the 1st round, there are studs out there at this position and the DE position is full of undersized players.
The Bills must hit a homerun with there 1st rounder this year
