That's because he wants to profit from working with GSP until he gets to fight him. He wouldn't be fighting at 170 if he wasn't planning on fighting GSP at some point.
This or there is a chance that Rory moves to 185 in the future....hes a fairly big WW to begin with and at 24 could fill out that big frame quite easily.
Funny what GSP can get by with due to his charisma and following. Rory tries it and gets chastised by Dana.
It can be equally argued that if GSP is such a top fighter why isn't he putting anyone away?
Dana disparity ftw....
GSP constantly sells 700,000 + PPV's....DW dont give a flying f*ck if he's doing cartwheels in there aslong as he continues with those numbers.
