That's true, a earlier Tyson could move, no doubt.
Anyway, the thing about Mike that is impressive here is that he is taken bombs..finally gets rocked and goes down, BUT his eyes are totally clear, haha...the guy is like a rock. I remember this fight and Mike just gave up...fighters get civilized, live in nice surroundings and some just don't want it. That is a very dangerous place to be if the guy across from you still does want it.
Even when Mike lost to Buster he got hit with many bombs...and great shots they were, again exceptionally skillfull shots, BUT mike was still putting his mouth piece in his mouth and standing up...
These guys, are the toughest guys in the world...... How many people can take hundreds of shots and show up for training the next day...My brother said his face would feel like a catchers mitt after hard sparring.
