8. Johnny Manziel (2012)
As a redshirt freshman in 2012, Johnny Manziel became the first freshman and fifth player in NCAA history to pass for 3,000 yards and rush for 1,000 yards in a season. “Johnny Football” became a national sensation, culminating with his Heisman Trophy award in 2012. After leaving Texas A&M, and as he slid down into the latter portion of the 2014 NFL Draft, amidst questions of his reckless personal style(s) on and off the field, he sent a text to then Browns quarterback coach Dowell Loggains, pleading his case for the Cleveland Browns to take him, saying “let’s wreck the league.” Instead, between a total lack of commitment to football, and an alarmingly increased abuse of alcohol, Manziel was out of the NFL by 2015.
