6. Johnny Manziel, Texas A&M
It’s safe to say that the SEC and college football have never seen a player quite like Manziel. From the first game of his career, he turned heads with his throwing ability, improvisational running skills, and his overall arrogance. He became just the fifth freshman in college football history to throw for 3,000 yards and rush for 1,000 yards in a season. Along the way, he was the first SEC player to have two games with over 500 yards of total offense in one season. Manziel also became the first freshman to ever win the Heisman Trophy. Even as he took a little step back as a sophomore, he always put on a show, drawing attention to himself, for better or worse.
The Browns made the foolish decision of taking Manziel in the 1st Round of the 2014 Draft. In the NFL, his lack of size and maturity quickly caught up with Manziel. He was involved in several off-field incidents that caused the Browns to cut ties with him after two seasons. It was all downhill from there both personally and professionally, as Manziel never got another chance in the NFL and had both his agent and sponsors cut ties with him as well.
