If Wladimir Klitschko wasn't allowed to hold so much during his career do you think he would have been as dominant?

I mean I have always liked Wlad but he sure does hold a lot and leans a lot which clearly snaps the strength of the opponent especially when the opponents were far shorter and there were times the ref did nothing or very little. Not blaming him for all of it his opponents were to blame for some of it and there were cases like with David Haye were he just threw himself to the floor and complained. I can help thinking in a least a few of the fights it could have been a closer and maybe the chance increases Wlad's chin would have be caught more times.
