I'm going to make my first boxing prediction (other than I choose Tyson Fury to beat Anthony Joshua but since that fight has not been made yet I could be waiting a long time for the result of that prediction.)
I have been watching Kell Brook since about his 12th or 13th fight and I have always been impressed with him. He is from the same training camp as Prince Naseem Hamed and has a similar style but a bit more conventional. I've always thought Kell Brook was impressive, lack of decent opposition is the only thing that let him down. I haven't seen much of Errol Spence because there is not much to see, he has never really been tested..Which leads me to believe Kell Brook wins on points.
