Say Arthur moves back to 160 and challenges Martinez, who takes it? To me it seems Martinez has many attributes that would give Abraham fits, and his style is right to follow the Dirrel/Froch game-plan, but he doesn't possess the physical advantages that those two fighters had over Arthur. Would Abraham be able to get close enough to Martinez to land his power shots, and could he KO Martinez if he does? Or does Martinez take a decision?
It will be similar to Pacquiao-Clottey. In that Abraham will sit in his shell and not be active enough to win rounds against a mobile and active Martinez. However, unlike Clottey, Abraham will have less respect for Martinez' power and will try to make it a fight. And unlike Pacquiao, Martinez won't be as aggressive and daring when launching his attacks. So yeah, a more competitive version of Pacquiao-Clottey, with Martinez taking a decision.
