I don't think you're giving him enough credit. Moorer was a beast, an extremely talented fighter and one of the best things to come out of the Kronk gym. And Morrison was very, very good himself and he fought a smart, disciplined fight against George. As far as Holyfield, even at cruiserweight, people were talking about him as the next big challenge to Tyson. Giving a great fight to a guy who was already an undisputed cruiserweight and heavyweight champion seems to me an undeniably impressive feat by George. And the fact that George hurt Holyfield but was never hurt himself, even when Holyfield landed something like 20 or so consecutive punches to him, says a lot. Foreman had his limitations in his comeback, but he also had incredible strengths.
