Hell of match,evander was in his peak and clay was a bit green,i go with the speed and reflexes of clay here by a hard decision
I think Clay could pull it out, but not easily. Holyfield has a hook, speed, a job, work rate, and stamina which will all make it a difficult bout. Clay has the jab, footwork, and skills to take the later rounds and the victory. Cassius Clay decision win
If Holy neutralizes Clay's jab (ala Norton) ....then Clay is in trouble. Clay by split decision with calls for a rematch. (see Doug Jones fight).
