Pretty clear from the title so lets start with an honorary mention. HM: TUF Live-really all this suffered from was the live format, which did not work out. #5: TUF ATT vs Blackzillians-much like Live this suffered from the format, where as Live was just production issues, this one was just a dumb format, in theory it could have worked but did not in reality. #4: TUF Carwin vs Nelson-Not only did Shane do nothing the entire season he retired almost right after. This topped with what I would call the most primadonna cast Ive ever seen, lot of complaining with not a lot of talent to back it up. #3: TUF GSP vs Koscheck-While watching Koscheck fail is fun, him and his team were easily the most unprofessional fighters ive ever seen. From Kos constantly trying to start shit with that male nurse, to the Armenians going on a snake hunt to catch a guy cranking one off in the shower. Also that whole thing they do where everything GSP's team is disrespectful but no one on Team Kos is ever lol. #2: TUF Rousey vs Tate-Guys and girls in the same house, how could that go wrong.....Again, just a whole bunch of dumbasses, most notably Cody Bollinger who misses weight against Anthony Gutierrez, AG then decides to take a bye, brag about making weight while stuffing his face, then misses weight himself giving his opponent a bye, basically making the one whole side of the bracket pointless. #1: TUF MCGregor vs Faber-Just the sheer favoritism shown to Conor's boy Artem ruins any aspect of competition from the show.....an entire season dedicated to Conor's dick waving. Thankfully Ryan Hall won and Artem continues to be the worst fighter in the UFC.
