So, is Carter trying to get bigger and stronger to handle the different demands of 1 tech? If that is the intention of the Bills, then Derrick Harmon as draft pick makes a certain kind of sense. It would give Buffalo a pure 1 tech and a pure 3 tech in Jones and Oliver (even though Oliver has filled in at 1 tech when necessary) plus a couple guys who can flip back and forth in Carter and Harmon. As long as they have enough beef to hold up in run defense, it gives them lots of flexibility, something the Bills seem to love.
