Matt Leinart
Leinart arrived in the NFL with a lot of promise but never delivered on the hype. The Cardinals hoped that he would be the man to replace Kurt Warner but filling the Hall of Famer’s shoes proved to be too much for the USC product. It wasn’t that he lacked talent because he had a great college career. That’s why Arizona made the Heisman Trophy winner the 10th overall pick.

But his partying didn’t help matters because he was a social animal. The media also picked up on this and gave him a difficult time. Unfortunately, Leinart fed the beast and didn’t learn to put his head down. He bounced around the NFL as a backup before he retired in 2013 following a disappointing career (via Fansided).
