What we've got here is a failure to titillate.
You can argue the merits of the main event at UFC 152 going down this Saturday in Toronto, but you can't debate its status as a foregone conclusion of a fight. There will be no intrigue. Jon Jones is going to beat Vitor Belfort. The rest of the event narrative unspools from that.
In fact, I can't recall two consecutive UFC pay-per-views that were topped with such blatant fait accomplis. Remember that Anderson Silva and Stephan Bonnar now headline UFC 153; taken together, these two events represent a climax of anticlimax.
So how do we get excited for UFC 152? Well, it's actually a pretty good card, if you're into that sort of thing. In fact, this is one of the densest fight cards in a while, thanks to all the refugees fleeing the rubble field of UFC 151.
Anyway, to help you preemptively separate the wheat from the chaff, here is the entire UFC 152 fight card ranked from least exciting fight to most exciting fight. Viewing information and various predictions sprinkled liberally throughout.
