Rewatched some older Silva's fights and noticed that sometimes his dodging and moving from the punches looked a bit strange. A bit amateurish? No, that's not the word I am looking fall. His defense had holes?
For example Anderson Silva vs Rich Franklin. Silva ducked under the kick? I think that's quite dangerous - you can get kneed or basically head kicked. I have never seen that someone would duck a head kick by leaning forward.
I think if Franking would have proceeded to attack seriously (because here he is doing who knows what) he could have connected. Basically by moving forward and giving volume ignoring Silva's dance.
Weidman did something similar - multiple times ignored Silva's dodging dance by proceeding to hit the guy and at the end - won by KO.
So was this Silva's bad move, maybe people started believing the hype a bit too much, or maybe he just new that Franklin is shit at kicking or kneeing people?
