VIDEO: Johnny Manziel vows to stop being a jackass

Rookie season was more than a little bit interesting for Mr. Football

The party and partying is over according to Johnny Manziel. The rookie quarterback has shipped plenty of criticism in recent days for some questionable off-field activities. The latest saw him fined for missing the walk through and being blamed for John Gorson's absence too due to an alleged late-night party ahead of the game with the Baltimore Ravens. However the 22 year-old has now come out and said he had nothing to do with any incident and that he's determined to clean up his act in 2015. Manziel has vowed that he'll be a changed man and there's be no horse play next season. He spoke to reporters in the locker room  to clear the air about recent controversies: H/T to Cleveland.com
