Not only do I not necessarily agree, but you can only judge fighters for their own Marciano would be a LHW these days. Frazier definitely a cruiser.
Zhang takes Tua in a phone booth, Tua is 5'10 no amount of freaky muscle barrel build overcomes that imo
Off the top of my head: Roberto Durán Julio César Chávez Henry Armstrong Jeff Fenech James Toney Riddick Bowe Joe Frazier Dwight Muhammad Qawi
Jacobs was very good at throwing combinations at close quarters like this. Just look at how he flurried to KO Quillin for example. Jermell Charlo is pretty vicious with his combinations and has a lot of pop on all his shots. Andre Ward was masterful up close and chest to chest.
Just because he’s 5’10 with a left hook doesn’t mean he’s an expert at infighting. Compare his punches to someone like Artur Beterbiev or mike Tyson, they aren’t as compact. There’s also the fact he doesn’t like body punches very much, as shown in the Chris Byrd fight.
As some other user said I'd pick Ibeabuchi over Tua. It's been demonstrated already! He has a granite but questionable chin (although he withstood the Tua bombs he complained of headaches which turned into his mental health outbursts), The power that can crack chins (he pounded Chris Byrd with that bolo punch), and he wasn't skillwise bad. He had a good jab, and a good defense, which is how he outworked and outboxed Tua. If Ike can protect that already stone chin from releasing the evil spirits, he's all set in a phone booth.
For middleweight it has to be Golovkin. Heavyweight is very hard because of a couple of powerful heavyweights with not the ATG Chin, like Tyson or Frazier. Lighterweights I would also pick Duran and maybe Inoui.
