I agree with Bob on that statement. For 8 years, Ronnie was the best in the world. Onstage this past weekend, Ronnie didnt look so great as a pro bodybuilder anymore, and thus, he should retire, as he is not going to attain what he did when he was the best. Simple as that.
If Ronnie does want to compete, anything below what he was might tarnish his image. Especially, if he isnt spot on like he was. Like it or not, comparisons will be made. Still, that is up to Ronnie. If he wants to do it for himself, by all means!
