I'm more concerned as to how Tunney could handle a guy over 190, especially one who was better than what Tunney faced in that weight range.
Loughran was a teenager and Tunney didn't clearly beat him. Levinsky was never "great" and was past his best. I don't see his scalp as even being equal to Maxim or Lesnevich. Gibbons was 34 and in his last fight. The smaller and older Greb fought Tunney on more or less equal terms. Dempsey had laid off three years before coming up empty in their first fight. Their second fight is clouded by the long count. The other names like Weinert, a green Risko, Heeney, etc. are certainly not in depth and quality up to the men Charles defeated. I think Tunney the best heavyweight of the 1920's, but I see him having a lot more trouble against post color line competition.
And the vast Majority at ringside had Greb winning or draw the second fight as well .. I actually see the Greb Tunney fights as a testament to how great Greb was and ... yes I'll say it ,, Tunney a little over ratted to me ..
I assume what you meant was that Tunney faced good boxers. Okay. He did, but so did Charles and Charles fought many more dangerous punchers. Tunney's big puncher opponents begins and ends with Dempsey, and possibly Carpentier. I think the point floating around here is that Charles fighting much bigger men and bigger punchers might not be relevant in a matchup with a boxing stylist like Tunney. Fair enough. My take is Charles' own jab and combination punching will tip the balance in this one over the more limited Tunney.
Loughran was a quality operator at a young age though. He'd already beaten Mike MicTigue, and beat Harry Greb just over a year later.
You've just named three losses and one of his worst performances. Charles has stated he hates fighting above LHW, because the extra weight made him sluggish. 190lbs was an awful weight for Charles. The lighter the better, hence why some of his most dominant fights at heavyweight were either against fellow light-heavyweights, or whilst he was fairly above the limit. Tunney, conversely, was a massive LHW, with broud shoulders and a big frame. Iirc, I remember something about him liking not having to make weight. Furthermore, Tunney faced plenty of people Charles' size, and he was better geared to heavyweight.
I think dragging in someone like Valdes is of questionable relevance regarding Tunney. Here is a list of the heights and weights that I could find of Tunney's major heavyweight opponents: Tom Heeney--5' 10"--203 lbs Jack Dempsey--6' 1"--190 & 192 Johnny Risko--5' 11"--192 Erminio Spalla--6' 1"--191 Harry Foley--(?)--190 Bartley Madden--5' 11"--189 Charley Weinert--5' 11"--184 and here are some that Ezzard Charles defeated: Joe Louis--6' 2"--218 lbs. Elmer Ray--6' 2"--192 Joe Baksi--6' 1"--211 Johnny Hayes--6' 4"--214 Rex Layne--6' 1"--203 Cesar Brion--6' 3"--197 Bill Gillian--6' 2"--211 Coley Wallace--6' 2"--201 John Holman--6' 3"--202 and Charles lost his only fight to Nino Valdes--6' 3"--210 So I can't see drawing pro-Tunney conclusions from any defeats Charles suffered against these type of opponents , as Tunney never fought such tall, rangy, and heavy men. The vast majority of Tunney's opponents were shorter than he was (and all of those on film except Dempsey who fought out of a crouch) with a far greater number middles and light-heavies.
People seem to be confused about my point. I didn't try to make a case for Tunney here, I just strongly disagree with the opinion that "Tunney didn't fight good boxers" presented by White Bomber. That's it, I'm well aware that Charles has much deeper resume and I'd pick him in this fight as well. It doesn't mean that Tunney didn't face good boxers, which was stated here not once.
