First of all, Bill Wallace wasn't all that good, I sparred against him a few times back in the 70's at Steve Fisher's and every time he tried to kick me, I beat the living daylights out of his foot with my nose. Seriously, i would pick Bill due to his wrestling background, If the fight were just stand-up, Roy Jones Jr's footwork would enable to beat Bill despite Bill's kicks, but once they clinched, Bill could use his wrestling ability to control Roy Jones Jr.
