Okami isn't marketable. White has already made it clear he no longer tolerates fighters who aren't exciting. And Okami didn't even have the success of Fitch, who was higher ranked when he was cut. Rankings and record don't matter if you're not exciting. Boring fighters waste UFC money.
Who ultimately decides what counts as exciting and what doesn't though? There are lots of paying casual fans out there who consider everything that is not a dogfight brawl boring. Should Dana just cut every wrestler and ground specialist altogether and make the UFC an unskilled version of K-1, to please the casual fans and make the most money?
