Ali paid a far bigger price. If he continued fighting from '67-'70, he would've beaten everyone in his path. A young, mobile Ali doesn't lose to Frazier in the first fight.
Tyson would've lost fights during his 3 years. His inevitable downfall was simply delayed by three years because of the prison stint.
That about sums it up...
