No. 1: Chris Lytle
Chris Lytle is the pound-for-pound toughest fighter in MMA.
With 18 defeats to his record, 16 have been by decision. The only two stoppages he has on his record were by cuts suffered by strikes from Thiago Alves and Joe Riggs, which is the only way a fighter is going to be able to finish the 36-year-old former firefighter.
Lytle has expressed interest in retiring, but he has no reason to, and his next fight will be against Dan "The Outlaw" Hardy on Aug. 14.
