The fight was a 29-28 for sure.
It can be made a case for both fighters to have won the 1st round.
I have the 1st round going to Sonnen (thus winning the fight),
just because of the way fights are being judged.
In terms of real fighting damage/effectiveness i would give it Bisping, but as Dana says, it is what it is...
Any way, what a mess by the officials.
