Agreed, and not all those guys were bums either. Buddy Baer was a monster who could really punch as was Abe Simon. Billy Conn was a lightheavyweight champion and a tricky fighter to catch. Al Mccoy was a seasoned veteran. The rest weren't all that good, but still thats a lot of decent fighters to take on in a 7 month period. It would have been like Evander Holyfield taking on a list like this in 1991: Bert Cooper, Alex Stewart, Francesco Damiani, Orlin Norris, Jesse Ferguson, Jerry Halstead, Mark Wills. Some of them were fringe contenders who were decent, while others were journeyman, but in either case it would have been a tough list for such a short period.
I beleive this term is a thing of the past for #1 guns in divisions. Back then, a fighter could make his own schedule. In modern times, politics demand a mandatory a year after 1 or 2 non-mandatory defenses, and that person is not always a bum.
It would seem that Holmes was one of the first champions to truly be held accountable for taking on contender substitutes.
No it isn't. One of these guys was the undisputed world champion, another was the #1 contender across the board, and a several others were legit top 10 contenders. Your claim has no basis.
Max Baer versus Tony Galento was actually billed as "Battle of the Bums", maybe just by the press though, not necessarily the official promoters.
While exchanging insults during their match, I somehow doubt Max Baer was that flattering to Tony. (Damn, I used to know a partially deaf lip-reader who could have interpreted what they were saying to each other on the film.)
Max Baer a top 20 heavyweight? Really? Many of the fighters didn't belong in the ring with the world champion. I can see those fighters on Louis' way up, but not during his reign.
