What MMA fighters do you think are competeing in the wrong division? Where do you think they should go?

GSP..........srsly i mean hes taken out nearly everyone in the WW division and at the end of the jake shields fight he was like "meh well maybe ill go up but i dunno i just finished my match so yeah i a pussy :)".........i mean i respect GSP and hes an amazing fighter but i mean whats he afraid of? sure anderson silva is a fair match but i mean why is he so afraid of losing? If he does lose it will only make him stronger and personally i think he has a high chance of beating anderson since GSP is a takedown master and Anderson's weakness is the ground
