You probably read that on Wikipedia and yes you are wrong.
Freddie Roach would not be wrong about something like that.
Georges said to Freddie "I think he's too big", that means a lot.. whether that statement is true or not, Georges isn't mentally ready to fight Andy.
I find this... laughable to say the least.
GSP is focusing on his fight at hand. To say he's not mentally ready because one of his trainers thinks a guy who fights at 205 is bigger than a 170 pounder is a stretch.
