Chuck has been knocked out 3 of his last 4 fights, Wanderlei has dropped I believe 2 out of his last 3, one of those to the aforementioned glass jawed Chuck. I wouldn't consider those 2 signature wins at this stage of their careers. The fact is that Rampage is a talented man, but he's so screwed up in the head that you can't be sure he'll be ready for any given fight. Thus I don't see him ever being considered one of the best in the business, especially not after the no show he pulled for his title defense.
