I think it was fine that Bam Bam never won a world championship. As many times as we heard him praised as a great worker "for a man his size," that size got in the way of his becoming a main eventer.
Face it, he wasn't just a big man.....he was a fat man, a very fat man..... more of a throwback to the pot-bellied, slow moving mammoths of pro wrestling in the 40's, 50's and 60's than today's sleek, athletic wrestlers. Those old guys knew how to work a match too, but can you imagine today's fan sitting still for a 45-minute match between two guys who did their training in bars? Bam Bam was the progeny of these guys.....a fact that was always going to hold him back.
Don't get me wrong, I enjoyed watching him work. That Survivor Series match in which he took out three huge bad guys before falling to Andre the Giant was one of my favorite PPVs ever. Talk about a grind-it-out old style wrestling match featuring behemoths.
Still, when the pro wrestling people needed a representative to lose to a pro football player at WM, whom did they pick? Bam Bam. Did you ever wonder why? I say it was because if the wrestlers needed to put up a sacrifice, they'd pick the guy who looked like the fat, out of shape man that most non-wrestling fans would think of as a prototype wrestler. The concept worked, too. Bam Bam was enough of a pro to lead Taylor to a surprisingly entertaining match; it wasn't LT who made it look good, y'know.
Bam Bam was good at what he did but his flabby physique is what kept him from world class status, imo. If Brodus Clay is the reincarnation of Bam Bam Bigelow, we'll understand why Brodus ain't winning no world championship, either. These kinds of guys can only go so far.
