Kelly Butler is a huge tackle with a lot of experience. He's a dominant run blocker, but he could use a little work on pass blocking. He's not the quickest of tackles out there and will probably be relegated to playing the right tackle position only in the NFL. Despite leaving early, he started 38 games in his 3 years at Purdue. He is quick with his hands and uses them to drive defensive linemen out of plays. If he can work on his pass blocking he can be one of the best right tackles in the game. Expect him to go in the 2nd or 3rd round.
