Larry Holmes, particularly in his second career (90s version. Not Tyson version). Against Mercer, Holyfield and McCall, he hung tough with some much younger, top men despite no longer having the mobility that had helped make him great.
He also has to be given a standing ovation for adjusting during the 2nd match with Shavers after that murderous knockdown. I thought Larry died. but he dug deep and found a way to win. First Weaver fight, awesome adjustments and turned the whole match around. He does lose some points for losing to Spinks back to back--although you could argue he deserved the nod in the 2nd match.
Film is out there on these guys. I would suggest for Tunney to maybe watch his fights with Tommy Gibbons and Georges Carpentier where his punching power is evident, fighting light heavies, which he too was. His heavyweight bouts with Dempsey and Heeney really displayed his ability to box. I loved the way he was zeroing in on Heeney's jaw with the right hand after having outboxed him early. Also when he got decked by Dempsey, his ability to utilize the ring until the cobwebs cleared. A real thinking fighter. As for Bivins, we all know what a great light heavy he was and his ability to box, punch and body punch. However, when he 'moved' to heavyweight, I don't believe he brought much of a punch with him, so he was always at a deficit. By consistently giving away height (he was only 5' 9") and often 30 pounds to his opponents, it was amazing how he navigated around these big guys to become #1 contender and duration champ in both divisions. He was a Canzoneri type. And by that I mean a guy who could box the punchers and punch the boxers. Of course, his abnormally long arms helped him compensate for any physical deficiencies with the big boys.
That's versatility. He could fight in various styles. Mind you he lost two of those. Cobe is after in ring change ups to win or even a change of style/strategy to win or go better in a rematch.
No disrespect to Larry, who was a great Heavyweight but his survival against Shavers was, more than anything, down to Earnie's inability to be clinical. If you got up against Shavers, chances were you'd win.
Seeing as he won those fights when he lost previously, I'd say he did a good job adapting. It's not his fault the ref did not penalize him. The point is he used a different game plan from the other fights and his opponent were frustrated by these change of tactics and lost. He made adjustments and they didn't.
Ali was the most analytical and fastest thinking Heavyweight of them all. Many times, he changed strategy during a fight but Zaire was utter genius.
That's true. He wasn't the best at executing his game-plans, but at least he kept things interesting by trying something new. Actually, in the cases of Liston and Frazier, those are the only two fights I know of where he fought like that.
Yes and no. It was Shavers who made adjustments in the rematch. The first fight was a complete blow lopsided win for Holmes. Shavers worked on timing his overhand right and worked on pacing himself so that he didn't blow his load early and wasn't simply chasing after Holmes the whole night. In the rematch it was starting to look like a repeat until the infamous knockdown. Holmes was on jelly legs. Rather than sticking and moving with a low left he began throwing his own right cross to target the growing cut and swelling in Shavers' eyes. And the only person to get off the floor to beat Shavers up to that point had been Lyle, who received a long count in his hometown of Denver. Norton stayed down. Roy Williams stayed down. Ellis stayed down. Smith and Gullick stayed down. Just about any opponent with or without a recognizable name/ranking that Shavers floored stayed down or was stopped during his prime. It wasn't until after the 2nd Holmes fight when he was old, discouraged, and heavily shopworn that you started seeing guys get off the floor to beat him. This is a myth that Shavers couldn't finish guys and was a crappy finisher. I mean, the bar was set exceptionally high for him with the iron chinned Ali, Holmes, and Quarry being the 3 biggest names he failed to KO. To be fair, he could get wild, but his KO% does not lie.
