I think he and Gilbert will compete in the DT pool along with Heard, Troup, Johnson and anyone else they bring in- Carrington and Gilbert will both probably play at around 300-305lbs give or take 5lbs so they may be considered a little undersized but they are both really strong and will be really quick compared to most DTs - I think DW likes a very fast defense and believes in platooning his defensive line and having at least 9 DLinemen
M Williams, Dareus, K Williams, Merriman could be the first line with Kelsay, Carrington, Gilbert, Anderson being the second then maybe S Johnson being the 9th guy- of course all we can be pretty sure of now is that M Williams, Dareus, and Kyle Williams are starters after that everything is up in the air depending on how people return from injury, Free agency, and the draft - after the starting 3 there are 13 players on the Bills contending for 6 DL positions that's not counting anyone we bring in from FA or the draft.
