Anderson does a little taunting to everyone he fights.
It’s just that he goes overboard and refuses to engage with guys who are submission threats. Just look at his worst instances of clowning:
-Thales Leites
-Demian Maia
-Chris Weidman
With those guys he kept very far away, and just hit them with flashy strikes (especially kicks) from the outside and would circle the ring and move back as soon as they tried to get into closer range. It looks like he clowning and taking risks, but really his hips and lower body are far out of reach for a takedown, which is what he’s really scared of with those guys. I mean, he was explicitly telling Weidman to stand up with him and not take him down.
The only guy out of the three who didn’t let him pull off that strategy fully was Weidman. It wasn’t the same as Silva’s fights with Maia/Leites, in that Chris was landing his strikes.
Also, every time Anderson faces the prospect of fighting a good wrestler/grappler he is strangely uncooperative before the fight. Think about Chael 2, what Dan Henderson said about Silva turning down a rematch with him, and his no show of a press conference for the Weidman fight. Not to mention his managers and even him saying Weidman wasn’t ready for a shot, but also saying they would be open to fighting Nick Diaz of all people (and Luke Rockhold, Cung Le…).
DON’T GET ME WRONG: Seeing what Anderson did to Dan Henderson, a great wrestler, with none of the clowning around, I think Anderson should have been able to beat Weidman, or at least had a more competitive fight (Chris could have got a sub or a decision even if Anderson fought him like he fought Dan). And until the knockout it really looked like Chris was in trouble. He was definitely getting played to a certain degree, even if he was landing and scoring–he wasn’t going for the takedown. But I don’t think that Silva’ “clowning around” was because he took Weidman lightly, I think it was the other way around. Anything to avoid being taken down, including clowning with his hands down.
