And this is a perfect example of why sparring means absolutely nothing when it comes to predicting the outcome of a fight.
At this time , Tyson was probably near his peak, (McCall was young, fit, seemingly mentally stable and not too shabby either.) and if they met in the ring:
1. No headgear. This discourages head movement and Tyson's head movement in fights was exceptional.
2. Smaller gloves, this helps Tyson with the torque on his punches
3. A referee wouldn't allow anywhere near as much clinching and holding. That is so tiring for the smaller lighter guy.
I thought McCall looked pretty damn good as well. And looking at this, it makes you wonder why he had to wait so long for a title shot.
