For a team that finished last season 4 & 12 the Buffalo Bills obviously have a lot of holes to fill. And with one of the most pourous defensive units in the league it's no wonder the Bills concentrated heavily on defense. Seven of their nine total picks over the three days of the draft were defensive players. Their top pick, third overall, is a great one. Marcell Dareus can play any position along the defensive line. Playing against some high profile competition while playing at Alabama Dareus showed he's a versatile player, being able to stop the run and rush the passer. He fills one of the Bills critical needs.
