He said in the post fight presser was that he was waiting for Rivera to get up but was too eager. As much as you all hate the guy think about it for a second and I think I believe him. He held that Thai clinch for a good few seconds and Rivera was getting up and I think Bisping just fired too early. He was waiting and waiting and as Rivera was getting up he realised what Bisping was doing and just held it.
As for his after fight antics he was fired up and hurt 'emotionally' lol as he claimed. Yeah he acted like a dick but what can you, do hes not scum though. He's a british fighter who you dislike greatly
