13. Johnny Manziel
Johnny Football has been a distraction to every team he has ever been on. While in college it was acceptable as he was the best player in the country. However, when he made his way the NFL and failed to produce, patience ran out.
While out injured during the 2015 season, Manziel traveled to Las Vegas to party. While living it up, he posted a picture of himself at home with his dog. This was supposed to throw the Browns off the scent, but it didn’t work. Manziel was eventually cut after just 2 seasons and never got another NFL job.
