I think a lot are being biased, I don't see why people hate on the guy so much because he probably is to this day the most exciting & ferocious H/W to ever live.
The guy had unbelievable skill, speed, power, his head & lateral movement was like nothing I have ever seen before. Everything about the guy is underrated & he really did help develop & influence dozens of fighters. His jab for a shorter guy was world class & his combinations was blistering.
I think based on styles he'd of certainly gave Vitali a right go. People mention the size difference but if anybody could of ducked/dodged/weaved there way into range it's Tyson. At his best he was seriously sharp & people do not realise or should I say appreciate his ring IQ & skills.
