Honest question. McGregor is at 170 at the moment coming off a win. George's went out on top at 185 but has admittedly dropped size since then on purpose. I can only vouch for myself but as a lifelong fight fan I have no interest in the McG vs Khabib 2 right now. I want TFerg and Khabib more then any other 155 matchup.
GSP vs McG as a main event on an end of the year card. I mean come on take my money please. Plus it sets up huuuge money fights down the road either way and no matter the outcome you still get your McG Vs Khabib 2. Win, win, win win
