Doesn't much matter...Coleman and Randleman, like Tito Ortiz, are guys whose time in the sun is pretty much coming to an end. Coleman and Randleman dominated with a straight wrestling/GNP game for a while, but never evolved past it whiel top guys either learned to defend the takedown or submit them. Randy managed to evolve, and so did Matt Hughes, but straight Hammer-style fighting is going the way of straight BJJ. Not enough versatility.
I think Pride keeps guys like them around because they are mean-looking, have famous names and make better fighters look good.
