I thought Callum Smith looked very good against a seasoned pro, I think he has a very bright future. I thought Kell did ok, he does need to face some better quality opposition and it will count against him if and when he fights Alexander.
I really like frampton, he has a inner fury that I like and his punch picking was very good, got tagged a couple of times but overall very good. Him versus Quigg would be a great fight.
Joshua, not sure about him. There is a lot too like, nice jab, good speed, strangely though I don't think he has real knockout power and as he moves up in class it will be interesting to see how he does I suppose long as he has enough to make people think he could do very well.
