well going back to the sharmba mitchell fight, mitchell was able to land 2 huge wide shots right on PBF's dome CLEAN. the reason he was able to was cause according to Jim Lampley PBF can see all punches coming at him except for the wide shots. But ZAB having done this in the past leaves himself wide open when he does go for the kill. so i think in order for ZAB to seriously hurt PBF he'll have to take a huge risk in leaving himself open for alot of people believe Zab is not as quick as he once was i too believe this to be true. So long story short if Zab does not end it fast then he'll be dominated all night.
