I take Naseem to win, but it would perhaps not be as easy as some think. Paul Ingle (who is a level below Scott) gave Naseem a lot to think about, and I believe Harrison fighting as a classier version of Ingle gives Nasem all he can handle. Nasem WU12 (8-4)
I'm afraid I'm going to get called a deluded Scot here but I think Harrisons , strength , chin and excellent straight punches are all wrong for Naz. Harrison on his arse early but grinding Naz down for a late stoppage.
I could see Naz winning a decision in the manner he beat Wayne McCullough. Harrison is tough enough not to be taken out with a single shot and his workrate could make it interesting.
I see this as an ugly, Hamed-Soto sort of fight with Naz winning on points. I think Naz would be wary of Scott's physical strength and would box his way to a points win. Afterwards, Harrison would complain that Naz didn't come to fight and Hamed would claim he'd hurt his hand, otherwise he'd have KO'd him!
Hamed is the classier fighter with more to his all round game than Harrison. I'm sure Harrison would have is moments in this fight though as Hamed would not be able to KO a prime Harrison. It would be a good fight but a (relatively) easy points decison for Hamed because he would be able to land far more due to his superior natural athletic ability. Scott Harrison was a tough, gritty, relentless fighter but Hamed had that little bit something extra to outbox him.
