I love the idea of a Pouncy Trade and move Beechum inside. I'm not real sure if the Steelers would be willing to do that but in the long run in makes a ton of sense.
There is also a chance that Beechum stays at LT..and we go with Decastro/Velasco/Pouncey/Gilbert.
In that scenario I can see the Steelers drafting a defensive back with the first pick. Two years in a row a player has "fell" to us and I think that if CB Darqueze Dennard fell to #15 we would have to pull the trigger on him. Also a chance of a trade down and FS Hasean Clinton-Dix being our choice in the back part of the 1st round.
