All 3 known to strike fear on the opponents and become a nightmare in the ring. Out of the 3, which fighters do you think would have dominated this era's HW division and remain on top? Hard to decide. I'll say Liston.
Tyson for me, although I think all 3 would be the cream of the division, I just think Tyson would clean the division out quickly and unify if within a year or so. Liston and Foreman would both be the man, I just don’t know if they would have the single minded purpose of Tyson to be undisputed.
