Considering pure fighting style without considering how Izzy would take the additional poundage . . . I'll pick Izzy either by points or T/KO. Izzy wins fights scientifically . . . he studies his opponents well, prepare a fight plan and stick to it. So not unless Cris John hurts him very bad for Izzy not to be able put his fight plan into play . . . I don't see Izzy losing this fight.
