4. Michael Vick, Atlanta Falcons:
We all know the disgusting story of Michael Vick. The unreal-athletic Atlanta Falcons quarterback pleaded guilty to federal charges in the Bad Newz Kennels dog fighting investigation. He had financed a gambling ring that did horrific things to pit bulls. The NFL suspended Vick indefinitely and the Falcons recovered a portion of his signing bonus totaling $19.97 after an arbitration hearing. They did not release Vick immediately but did so in June 2009.
As for the dog fighting ring, Vick admitted to financing several dog fights in Virginia, Maryland, North Carolina, and South Carolina. He also stated he shared the profits from the dog fights and that his accomplices killed the unfortunate dogs who did not perform well. Vick was sentenced to 23 months in federal prison. He returned to the NFL with the Philadelphia Eagles after he was released in 2009, but was required to put $1 million into an escrow account to pay for the care of the dogs he had harmed that were still alive.
