12. Richie Incognito vs. Jonathan Martin
The antics of Incognito didn’t help the Miami Dolphins during a tumultuous 2014 season. The troubled offensive lineman had a terrible relationship with Martin. He bullied the younger man to the point that Martin got fed up and walked away from the NFL.

Incognito tried to pass off his actions as leadership but that didn’t stop the Dolphins from suspending him. After losing both players, the Dolphins went on to an 8-8 season. There really isn’t anything good to say about Incognito from all of this. It was an ugly situation with no real winner.
