Incredible day for MMA. I'm shocked that Weidman pulled off the upset - I've always maintained that he deserved the shot but thought that Silva would crush him.
I don't believe that there was anything suspect about the finish: Silva simply ate a shot that was harder than he'd anticipated which took his legs out and the shots on the ground did the rest. I also don't think his clowning was anything out of the ordinary. If he'd recovered and gone on to win the fight nobody would have read anything into it.
Massive congratulations to Weidman for doing what had seemed to be impossible for so long.
