Abraham, Benn lost to Watson because he punched himself out against Watson`s high guard Abraham guard was more water tight than Watson`s was in that fight, Benn improved after that fight but went on to lose to a very open Eubank, that version of Benn wouldn`t have caught Abraham as much as he caught Eubank when he was stopped in the 9th round, bad form.
Abraham takes this one with a knockout in 7 rounds. He has a very strong chin, a strong gourd, and power to match Benn's. It would be a war while it lasts though.
