Michael Moorer Mike Weaver Chris Byrd Leon Spinks from Ali 1 Trevor Berbick Pinklon Thomas Tommy Morrison Oliver McCall Frank Bruno
Assuming those guys are at their pinnacle, he likely loses to most of them. There's a reason he outright stayed out of the heavyweight division with the exception of the one Ruiz fight.
I think he could beat Leon Spinks, Byrd and Moorer. They were small heavyweights and could be hurt. I think he might beat Bruno if he sticks and moves non-stop. Bruno was very strong, but also slow and ponderous an didn't absorb punishment well. Jones was not powerful at Heavyweight, but could hurt Bruno with an accumulation. I think Weaver, Thomas, McCall and Berbick have the right combination of strength and toughness to wear Jones down. I think Morrison has the speed and power to hurt Jones if he can get to Jones first.
Michael Moorer Jones by decision Mike Weaver Weaver by stoppage Chris Byrd Jones by decision Leon Spinks from Ali 1 Jones by decision Trevor Berbick Berbick by stoppage Pinklon Thomas Thomas by stoppage Tommy Morrison tough one to call but I think Morrison catches him and gets the stoppage Oliver McCall Jones by decision Frank Bruno Jones by decision.
