I think a sleeper pick has to be someone that you didn’t see coming. I have some suggestions. Not saying I would choose any of these players at #20 but I wouldn't rule any of them out.
Travis Swanson, center, Arkansas
Arians and Keim has both said more than once that the team has to become more psychical in the trenches. I’m have no idea how the coaches graded out Sendlein this past season but I doubt they thought much of him from a physical standpoint. He doesn’t get much push in the run game.
Brett Bielema has called Swanson the best center he has coached, and though that might simply be coaches talk, I think there is some truth to it. The last couple of years Bielema has coached guys like Peter Konz and Travis Frederick, and both of them were selected in the first two rounds. I think Swanson is a better prospect as he can pass protect very well, run block his opponent completely out of the way, make combo-blocks, get to the second level with ease, and does it all with good technique.
Morgan Moses, offensive tackle, Virginia
A lot of people are fascinated by the athleticism of Greg Robinson out of Auburn but really, Moses is not that far behind. I actually think he might be a slightly better pass protector but might not be in Robinson’s league in run blocking. Moses is close to the definition of a dancing bear, and again, I could see him being a target because of the desire to get more psychical up front.
Kyle Fuller, cornerback, Virginia Tech
Now, Fuller might slide to the second round due to injuries. His talent is clearly better than that, though, and with him and Peterson on either side the two of them could alternately be the cover corner and more of a playmaking type cornerback. They both have those abilities, and simply having them back there would make the job easier at the defensive line and a lot harder at the quarterback.
