Tyson via brutal KO1. The exceptional timing & accuracy, blistering speed & nuclear powered fists of Iron Mike would be too much.
RJJ would be wearing nappies for the rest of his life if he took on prime Tyson. Tyson ko1 quicker than Spinks.
The only chance Roy has of making it to the 2nd round is if it was the version from the Hill fight (by old time standards he would be a HW, but barely)
Spinks engaged Tyson, Jones wouldn't be that stupid and would look to box and be elusive, Jones lasts longer because Tyson finds it harder landing, how long I'm not sure
A little bit. As Jones was more mobile than Spinks,he may have lasted until the third or fourth round.
I cant see Jones doing anything more to keep Tyson off of him, including movement, and I think it takes less to hurt and demobilize Jones. I cant see Jones lasting too long.
