Point is, Weidman is a well rounded MMA artist and is dangerous everywhere, that's why he's champ. Yes, Vitor is a complete different striker than counter strikers Anderson and and Lyoto but, Weidman had no problems with either of the 2 best strikers in MMA today. Scary thing is, is that striking and boxing isn't Weidmans strength. His wrestling and TDD plays a huge role in his game.
Weidman can and will trade with the best of them all day, but if he gets one to the ground it's game over for Vitor.
