George was hugely over and is recognised by people like Ali and even James Brown as being an influence on their careers, but he didn't actually win the big matches. George was an incredibly important character in pro wrestling history, but he was quite small and never won convincingly.
Rhino may not have the influence George did, but he would have the raw power required to beat him. The crowd for this match would be hot to see George lose, not to see Rhino win, but that doesn't matter. Rhino wins this one with a gore.
