Saul is very fun to watch. Definitely going to be a hell of a force in boxing for a long time. He already housed the welterweight division and is now making a name for himself in the light middleweight. I hope he keeps moving up in weight class.
I wouldn't mind seeing him fight middleweight but I think if he ended up going anywhere beyond super middleweight he would be in trouble due to his height. Kid already has almost as many wins as Floyd which is very impressive at the tender age of 20.
He can definitely handle light heavyweight if he takes his time. Jean Pascal is 5'11'' and Tavoris Cloud is 5'10''. He definitely has the power, from what I have seen from him to make it. But you may be right.
I guess I got a little ahead of myself. I figured that most fighters would be around the 6'-6'2 range. 'If the champs are that short then he could do it. Especially considering Pascal only has a 1 inch reach advantage.
