Former college football star Johnny Manziel predicts NCAA's demise: 'It's only a matter of time'

Johnny Manziel was one of the most popular college football players of his era. He threw for 7,820 yards during his two-year stint as the starting quarterback at Texas A&M. He was named the Heisman Trophy winner in 2012, becoming the first freshman to earn the accolade.

Manziel became a household name and brought unprecedented attention and revenue to Texas A&M, but his rise to stardom was also riddled with controversy. He got caught in the NCAA's crosshairs when an investigation targeted Manziel's possible autograph scheme.
