I have to vote for GSP, we live on ths island and I've never been to BJ's island!
But where I think I'm more objective is in that BJ wasn't robbed last time! Sure GSP was bleeding in the first round, but so what, that's the only round BJ dominated... and it actually shows how resilient GSP is to have come back so strong... he did the same, but on two matches, with Serra... GSP, unlike what BJ believes, is no quiter, but he's intelligent, and if he takes a step back, it's to evaluate and change direction, not to quit!
Considering that they're both well trained, I'll go taboo and say that the machine GSP will overcome the brawler BJ!
