It's a shame people questioning Norton's punch resistance in this thread. He had a good chin, just not an elite chin and couldn't handle those with elite power (Foreman, Shavers). I'll follow the consensus and pick Tyson within 2
As much as I admired Ken,I can only see an early Tyson victory here. Styles maketh the fight,and Tyson's was all wrong for Norton. Ken was a far tougher opponent for Muhammad Ali than Tyson would have been,imo,but Mike would blitz Ken every day of the week.
Norton was bad with stong punchers he needed a guy he could box and didnt have a lot of power, Tyson ko2
If Shavers could stop Norton then a harder puncher and much better finisher in Tyson would obliterate him.
Don't forget prime Tyson was also much quicker, quicker on the feet, heavier, better handspeed, better stamina, better chin.
