10. Diego Sanchez
Record: 23-4
Promotion: UFC
Age: 29 years old
Reason:
After being thoroughly dominated by BJ Penn in his one and only UFC lightweight title shot, Diego Sanchez decided to make his return back up to the welterweight division where he had been so successful in the past.
But his return was spoiled by then-undefeated fighter John Hathaway, who scored a unanimous decision over
The Ultimate Fighter season 1 victor.
Diego knew he needed a change, though, and decided to join back up with Jackson’s Submission Fighting for his fight against Paulo Thiago in October 2010. The move seemed to work, as he was able to win the bout by unanimous decision.
Sanchez might be even higher than No. 10 on this list if he had been as dominant in his most recent bout against Martin Kampmann. Though he ended up with a win on his record, many have criticized and pointed to the judging of that fight in particular as one of the more poorly-scored fights in recent memory.
