The fact that they haven't faced "true oppositon" is what makes prospect fights so exciting. They have so much to lose, anything can happen, and you can see how the future of your weight division will look. Prospect watching is what boxing is all about. I think Peterson will shock everyone. Peterson is the future, i think. He is slick, strong, and is very very busy. Bradley is a bruiser though... I think it comes down to peterson getting his chin checked... if he is tough, he gets the UD.
Gotta say Bradley based on competition and how he won. But he does leave himself open alot especially after he throws, so if Peterson can really box against good opposition he can work him out.
Peterson is nothing special. I also think Bradley get too much credit for skills he might lack, but he has very good fundamentals that should make him overcome a busy Peterson either by UD or by late stoppage.
