Good point, but remember that Ronnie was light years ahead in size. I'm willing to bet Ronnie could come in with a slimmed down version and look great but no one would accept his smaller not so freaky bod. Also he has many tears that would be noticeable.
But here is the thing, he is 8 time Mr. O. He doesn't need to prove anything to anybody. I believe this is where having a grounded family life, like Haney has, comes into play. Ronnie doesn't have that. All he has is bbing, and that defined him. Haney was Mr. O and a husband, and a father, with support from his family. Once he left, he was a husband and father, and was grounded.
All Ronnie has now is injuries, Sandows, a lot of kids and a supp business...What he could do is put the same focus he had when he was winning into his business.
