Miami Dolphins running back Ricky Williams was considered a franchise back just 10 years ago as he came out of the University of Texas.

Williams, now 31, is simply looking to re-establish himself as a solid contributor and rebuild his legacy before he moves onto his next career: a physician.

The running back has tested positive for drugs numerous times, earning himself several suspensions from the NFL. He ended up landing in the CFL for a couple of years before making his way back into the league.

However, Williams stressed that life is full of ups and downs and that he believes he has grown so much as a person.
