Welcome to Pro

I think Tyson in his prime was no match for Ali in his, however as you point out if they had met at say 20 years old Ali would have struggled.

Kovalev will shut him down on the inside and Ward can’t hope to go the full duration

Tyson didn’t have as much mental stamina. Ali could easily frustrate him with all the usual antics then swoop in for the knock-out.

Tyson hit so hard that even if he missed 9 out of 10 punches, he’d really do some damage.
