Not really... Rahman could very possibly KO him if he landed his best right hand like he did against Lewis, but he has never landed that good a punch on anyone since Lewis despite how many mediocre opponents he has fought... I think Wlad would handle him, but if Rahman came in absolute peak condition and could press the action hard for a good 8-10 rounds he would have a chance to wear Wlad out first..Mind you Rahman doesn't have a great chin himself. Wlad would probably land his right hand first and consistently en route to a stoppage just liek the one today, thats the most likely outcome really. It seems Wlad has got some of his shit straight, but you never know.. he may only have fought with that kind of conviction because he knew Byrd couldn't hurt him. If he lets his hands go against a good puncher that's where he's in danger, imo. Once he commits to the attack, he risks punching himself out, and can be in trouble if he doesn't hurt his opponent enough, early enough. That's my take at least. You could tell against Sam peter, he never commited to trying to hurt him, or get the stoppage.. Because he knew he was in against a dangerous puncher, and he didn't know how much he could hurt him.. I think with Rahman Wlad knows he could hurt him pretty badly, and would just do it early.
