13. Collin Klein, Kansas State, 6-5, 226: He is the 2013 version of Tim Tebow. Some NFL teams think he would be a better tight end than quarterback. He started out as a wide receiver. Klein is not a very talented passer, as his delivery and accuracy are lacking. But he is quite an athlete, he has really good size and he can move. Klein is tough, and he is a natural leader.
