Seen nearly all his fights and i never see him fighting going backwards he would always stand in front of his opponent even when taking a beating he'd be upclose. Not like ali or other fighters he would never go backwarrdss
just wasnt his style to do so. But he has shown moments fighting with his back against the ropes such as against buster mathis.
he was short for a HW...not sure, but i assume he didn't have the reach to fight the jab game like wlad when he was in his prime he had excellent head and lateral movement
i think he had to against holyfield, wasn't holyfield bullying him around the ring a bit in both fights?
During his prime (with Cus) he never took a beating. His defense was great combine with his ability to step-in in front of his opponent was second to none. Anyway he was too short to fight his opponents by outboxing them.
