5. Johnny Manziel's Bad Boy Behavior
Texas A&M quarterback Johnny Manziel is the first freshman to win the Heisman Trophy, the award for college football's best player. But Johnny Football also seemed to have an unfortunate nose for trouble in 2013. He left the vaunted Manning Passing Academy early, tweeted that he couldn't "wait to leave College Station" and underwent an NCAA investigation for allegedly selling autographs. (The NCAA ruled that he had "inadvertently" violated rules.) For that final indiscretion, the 20-year-old was suspended for the first half of the first game of the 2013 season.
