Is the problem that really tall skinny guys wanna fight in lower weight classes, or is the problem that tall, filled out guys want to cut a shitload of weight to fight well below where they should? It's pretty obvious that Violent Bob Ross is a very skinny guy on fight night, not just on the scales. Now compare that to someone like Till, who is not a skinny guy on fight night. He's massive, making it clear he's just killing himself in order to get a huge size advantage in his weight class.
As of right now, I see no controversy with this Bob Ross guy's size advantage. He's just a skinny guy, like O'Malley. If he puts on 20 pounds of muscle and then tries to keep fighting in the same weight class (or a lower one), then I'll see a reason for criticism.
