I really am confused by the uproar on this one. I thought Chael took the first round last night, I've rewatched it in the cold light of day and I'm still convinced that Chael takes the first round.
Two takedowns, a few good shots, about a minute of having Bisping up against the cage, working for the 90 or so seconds that Bisping has him up against the cage and slightly losing the brief standing exchanges.
Bisping gets taken down twice, shows how great his wrestling is to pop back up, attempts a takedown, fails. Holds Chael up against the cage and works, is held up against the cage himself and does not work, grabs shorts, breaks and initiates a striking exchange with no clear winner.
I could possibly see how that may be a 50/50 in some peoples eyes, I would personally have given it to Chael for being the agressor and in my opinion getting the better of the exchanges - where has the all the "OMG ROBBERY!!!!111" butthurt come from?
Edit: I think it might have something to do with the pretty awful commentary by Joe Rogan on this one.
