This is why VegetaGD wanted you guys to specify when Chuck's "Prime" was. I consider his prime to be his 7 fight championship reign since he lost two of his 3 fights just before that. According to you now, Chuck's prime is his whole career until he started losing regularly? That's typical of this kind of argument and why I find it such bullshit. "Prime" is whatever you want it to be that best suits your argument.
Shogun, Wand, Arona, Little Nog, Hendo and Rampage were probably the top LHWs in Pride while Chuck was UFC champion. Chuck never fought any of them except Rampage till late in his career and Rampage stopped him both times. Chuck fought excellent grapplers and one average striker while champ. Beating excellent grapplers who couldn't strike is why he rates so highly.
You're basically saying Prime Chuck carried over to his title reign even after being stopped by both Couture and Rampage the first time. But, when Chuck lost to Rampage the second time, suddenly his chin was cracked so everything else doesn't count? Even tho losing to Jardine was less than a year after "Prime Chuck" pasted Tito for the second time? Gee, I wonder how "Prime Keith" would do against today's LHWs?
