UFC Minute: GSP Returns to the Octagon

GSP returns to the octagon versus Bisping? This seems like an attempt to throw anyone at Bisping who is not a Top5 MW contender. GSP is a WW who hasn't fought since Nov 2013 so it's a win for him either way, moving up a weight class (15lbs) against the MW champ he's supposed to lose. What do you think?
