10. Josh Koscheck
People have been not liking Josh Koscheck since the first season of the Ultimate Fighter. The successful collegiate wrestler was 2W-0L when he joined the inaugural cast of TUF, and proceeded to make an enemy of many who shared the house with him.
Most notably “Kos” pissed off lovable trainwreck Chris Leben on the show, and ended up eliminating him from the tournament with a “lay and pray” victory.
Paul Daley wasn’t a big fan of Josh Koscheck, especially after the two met at UFC 113. Kos won a decision victory that night, but Daley infamously gave him a good solid shot well after the fight had ended.
Those who don’t like Koscheck will be happy to know he lost his last 5 fights in the UFC, and while he signed a multi-fight deal with Bellator, he has yet to actually fight for the promotion.
