Jefferson, who is 5'11 and 212 pounds, had 113 tackles, seven tackles for loss, three sacks and two interceptions as a junior in 2012 for the Sooners. Oklahoma lost, 41-13, in the Cotton Bowl on Friday to the Texas A&M Aggies. ESPN.com ranks him as the No. 5 draft-eligible safety in the country.

Stills had a big year for the Sooners, hauling in 75 catches for 892 yards and 11 touchdowns. The 6'1, 190-pound junior from Encinitas, Calif., grades out as ESPN's No. 14 draft-eligible receiver. He had four touchdowns, including the game-winning score with 24 seconds left, in a 50-49 thriller against the West Virginia Mountaineers on Nov. 17.

The 2013 NFL Draft begins April 25 and runs through April 27.
