2. Khalil Mack, LB, Buffalo
6-foot-3, 244 pounds, Sr.
Mack debated entering the 2013 draft but chose to return to get his degree and try to help the Bulls back to their first MAC title game since 2008. Mack has the ability to warrant being picked in the first three rounds. He led the Bulls in tackles and is currently the NCAA active career leader in tackles for a loss (56). His ability to disrupt offenses will attract a lot of scouts to Buffalo.
