I agree with you with the exception of #2(well, at least the first part of it)
Chael is not smart. Smart people usually don't run their mouths as much as he does...and when they do, they also usually know what they are talking about. In an interview he said that Silva is a discrace to the sport because he wears his hat backwards. Srsly br0!?! He is steady running his mouth about other cultures when he knows little to nothing about them. Shitty personality aside...dude is a beast in the octagon. However Silva is going to beat the breaks off of him.
