Tyson's kind of like Naz, you can't look at their whole careers cause they just let themselves go, you've just gotta look at that point in time when they were at their peak (no matter how short a time period that might have been)and if you do you would have to admit that they would have likely been too much for anyone around their weight class no matter what era. All the Tillis fight really showed was that a poorly motivated Tyson could still cruise against an Ali type opponent (not quite of Ali's caliber obviously but still Tyson would have been far more motivated for an Ali fight). Same with Naz really, I'm not sure how anyone could watch the Jose Badillo fight and think Morales could beat that Naz. And that's obviously just one example.
