i think since BJ went up a class to fight GSP then GSP should go up a weight class and fight silva. i think that would really test him
sorry dude GSP is an amazing fighter but he would not stand a chance against silva. not taking any thing from GSP. i think some of the other 185 guys might be a better match. GSP is just too small his wrestling is good but he does not have the size or strength to match Silva in a take down fight. striking hands down goes to Silva. again GSP is great its just mathmatics. BJJ also has to go to Silva. look at his camp. all legends. i think a good match or pairing would be Henderson and GSP. both wrestlers GSP has the better BJJ and prob striking Hendo is bigger and is a tough SOB.
GSP and Silva would be a big let down.
just my .2
