IMO, RB and LB (in general, not necessarily MLB) are the two biggies. We should trade up in the first round and make sure we get a 1st round RB and a 1st round LB.
CB is the next biggest hole, I think we'll sign a mediocre veteran (similar to K Thomas).
I think we're okay at DT, but I think we'll draft at least 1 DT later on in the draft.
