I'd fancy a hypothetically in shape 40 year old Tyson against current Canelo, maybe even 45 year old too, but 55 is much too far, obviously. a couple of high paced rounds would leave Tyson a long way out of gas.
Why is this poll not 100%? Canelo would put Tyson in the ground. It’s not a fair comparison. A prime elite fighter versus an old retired guy who smokes weed all day? Come on, man!
