I'm not really a fan of the Bleacher Report, but I think from reading the intro to the article that the author's point was that the "ideal body type" for a wrestler has changed over the years and a lot of guys from the past might get overlooked in today's scene. There was a point a few years ago where every new guy that popped up in WWE seemed like he was a model for Men's Health magazine. I beleive his fat jokes are supposed to be from the point of view of WWE upper staff that would be evaluating talent.
My thoughts...pretty much everyone on this list could get over and would find a way to make it to the "big leagues." They would just have a longer road to WWE. Maybe they'd have to work the indy circut for a while and build up a reputation. True, WWE is using guys like Punk and Bryan, but those guys had to put in a lot of work before WWE thought about bringing them in.
