12. Greg Hardy
Hardy made the Pro Bowl in 2013 when he played for the Carolina Panthers. It looked like he was on course for a decent professional career but then the police arrested him. This was another horrible domestic abuse case. He battered his girlfriend before throwing her onto a pile of guns. It’s a surreal situation but it rocked her world.

His name instantly became dirt in the NFL and they suspended him. He received a second chance in Dallas but the franchise gave up on him. Hardy trained in MMA and joined the UFC but the fans reviled him. They booed him every time he featured until finally, the promotion cut him (via Deadspin).
