I love GSP, i think he is a monster, he has a great future in the sport no doubt. I do think he a decent chance with walking away as champ. However, i have no reason to discount Hughes, the guy has proven to a a true champ time and time again. I wont be surprised if GSP gets the win. But Hughes has beaten him before, and shown a lot of heart in the sport, and i do beleive he wants this win very badly.
As far as his personality goes. Im not a huge fan with how he acts, i do think that it gets exaggerated a bit though. He does act very cocky, but then again he does have a pretty remarkable recored, Not that it gives him the right.
He has admitted that GSP is a fight he needs to take serious, and the he is worthy for the fight.
Matt Hughes is on top right now, seems like everyone wants to see him fall, i know its going to be a war come this saturday, i look forward to watching both men fight for the belt.
Lets just let the best man win.
