Frazier ranks a bit higher.

Tyson cleaned the late 80s. Frazier cleaned the late 60s, which was a better division. Also, Frazier never lost against someone like James Buster Douglas. And, although he lost the trilogy, he defeated Ali one time.

I have the impression that, head to head, it could be a very close war and might go to Tyson. That's why Frazier ranks just a bit higher.

#7. Frazier
#8. Tyson
