This will be a war and though BJ will be in top shape he can't match and sustain the pace GSP will set for this entire fight. He will wear down as the fight progresses and GSP will finish him late 4th or early 5th by TKO.
I'm with GSP too...Pen at 170 was never the best Bj we've seen. I also hate hearing fighters say how they're going to kill each other...too unprofessional for my liking. BJ talks a good fight but will not win.
