Khan can outbox him for sure. Guerrero would use a pressure gameplan...If Khan had good ring generalship and ring smarts it would be a walk over... however...
I think Guerrero could be all wrong for Khan, style-wise. He is probably a better version of Peterson in ways in that he is a decent come-forward pressure fighter with a good chin and stamina. If Khan just backed up/ran the way he did vs Diaz and Peterson, Guerrero would probably cut off the ring and walk him down and beat him up on the inside. Although Khan could outbox him if he used his natural skills.speed effectively, but he rarely does.
Guerrero may not be a ko artist but you dont need to be to hurt khan especially now as he seems shot. Guerrero hits harder than diaz and limond both of whom dropped khan. Amir struggles against good pressure fighters he just doesnt fight well inside and does not hit hard enough to keep anyone off at top level. When was the last time he stopped a good fighter or even hurt them? He dropped maidana a few years back to the body yet he got back up fine, how often do fighters recover from body shot kd? not very often
