Bisping's reaction after the fight was in very poor taste. Ok adrenaline is high and he was clearly euphoric to have beat the guy...but that was it, his fists had done the talking no need what so ever to go over there and say shit in his annoying accent.
Even if he felt Rivera had crossed a line with the things he said, you beat him, finished him at that....punched him so many times he couldn't even defend himself and the ref had to save him. What more can you achieve by trash talking after the fight? You had said everything that needed to be said by TKO'ing the guy, leave it at that.
The illegal knee was bad enough, outrageous and by all rights he could have lost the fight because of it (he should be thankful Rivera manned up and carried on) he put the guy away in pretty convincing fashion at the end...I really don't understand the actions post fight, it was trashy and classless in the fashion Brock did post Mir victory.
Bisping let himself down big time after the fight ended, but truth be told Bisping just raised his profile again, more people will now wanna see him get ko'd which means more people will pay to watch him fight which means he will be a bigger name and bigger draw in the sport (often the 'HEEL' character is equally as important, more so even, than the fan's hero when it comes to promoting and selling fights)
