depends whether he bulks up for the Bisping fight, or simply goes in without cutting.
He has long said that if he moved up, it would be a permanent move- citing Roy Jone's move up to HW and inability to perform with the same reflexes and speed after cutting back down.
GSP has always been very smart in managing his health, and his career. So, if he is bulking up for MW, he surely isn't ever making 155... might still be able to make 170 though.
But honestly, he's already cleared out that division in his prime, beating the greats twice even. Sure, new stars have emerged, but emerging stars they are. Lawler drew what, 7000 seats and 200k buys? cant imagine fans are lining up to watch Woodley after booing him out the building last time around either.
Woodley is going to have to rebound big in his next fight to earn a spot against GSP- the top PPV grosser in MMA history.
