UFC could come back, but there is no denying its on a cold streak. A lot of its success (like any fight sport) depends on great matchups which the public can buy into. MMA had that for a while but the momentum is slowing down because some of the old guard are being cycled out. The one problem I do see for UFC is the behaviour of one Dana White. If he doesnt change his act, UFC will lose the credibility it worked so hard to gain.
