High School, he was a dual-threat quarterback who threw for 1,827 yards and ran for 1,527 yards and tallied 39 total touchdowns. HIs brother, Charles, is a defensive back at UC Davis.

He played at Foley (Ala.) High School with receiver Julio Jones. Their battles started much earlier, however, with games of hide-and-seek.
CB Tyrann Mathieu, LSU: Early entrant. The big circus of this year's Combine — other than Manti Te'o — will be Mathieu. A top Heisman Trophy candidate, Mathieu was kicked off the team in August for failing multiple drug tests. Then, he was arrested on drug charges in October. Last month, he told ESPN that he "abused" marijuana. In 2011, Mathieu (5-9, 175) was a Heisman finalist — the first defender invited to the ceremony since Charles Woodson.

He joined Marshall Faulk, Kabeer Gbaja-Biamila and Kirk Morrison as the only three-time first-team all-conference picks in school history. Most schools recruited him to play corner; he chose San Diego State so he could play receiver. He played receiver for two weeks before being sent back to cornerback because a senior tore his ACL.
CB Brandon McGee, Miami: McGee (6-0, 197) intercepted three passes in his two seasons in the starting lineup. He lost his starting job at the start of fall camp, with defensive coordinator Mark D'Onofrio trying to light a fire under his senior. It worked. McGee's gone through more than his share of hardship.

His 34 pass breakups rank second in school history — a remarkable figure for a three-year player who rarely was tested this season. He was the top-ranked safety in the 2010 class coming out of Stanhope Elmore High in Millbrook, Ala.
