For what it's worth, I think his self confidence is huge and, in boxing you need a bit of that.
He's definitely not the greatest of all time but, he is big and he is tricky - I don't think we've got a heavyweight at the moment that can unravel him.
........he plays his game really well.
It's going to take time for him to get a bit older and, for a younger puncher to come up and surprise the division.
I see him getting put down a few times in about 5yrs then, coaching some decent prospects.
