I know this much.... TUF 19 isn't the answer.
I think a tournament once or twice a year would be cool, some multi fight events... Maybe even have a championship tournament? Champ has to fight #3 contender, #2 and #1 contender fight, winner fights winner... for new belt perhaps?
They've got too many newcomers from TUF shows, these guys aren't all worth watching. I'm sick of Joe Stevenson and Keith Jardine being on more than original UFC fighters. Maybe throw in a TKO only match... no time limit. Fight to the death so to speak. SOMETHING new!
