Brandon Thomas, Clemson LT.
We've all heard of Clemson University's Sammy Watkins of course. He's considered the top prospect in the entire nation at wide receiver and in a class replete with talent at the position. He and in-state rival Jadeveon Clowney get all the (non-quarterback) press, and frankly it's unusual for the state of South Carolina to have so much attention on multiple kids heading into the draft.
UPDATE 4/8/14 - Brandon Thomas tore his ACL in training and will miss any football action for 2014.
