According to CBS with the 1st overall pick the Tampa Bay Buccaneers select

1. Tampa Bay Buccaneers - Leonard Williams, DT, Southern Cal: The Bucs could very well roll the dice on one of the quarterbacks but without a sure franchise passer available, don't be surprised if defensive minded-head coach Lovie Smith pushes for Williams, who could team with Gerald McCoy and Michael Johnson to give Tampa a fearsome front. The 6-5, 290-pound Williams has been my personal top-rated player since October. He is a physical mismatch too quick for interior linemen and too powerful for offensive tackles.
