I think they pretty much have the right thoughts for this one. Arreola has a puncher's chance, and no doubt he is heavy-handed when he can land the shots, but the main problem is that he's going to struggle to get his fist to the Klitschko chin. The Klit-jab (TM) is almost impossible to get past, and that's the big obstacle for Arreola is not to ship too many punches whilst getting his big punches off.
