Moorer by mid-to-late rounds knockout at LHW. Roy up on the cards at the time of the stoppage. Jones by safety-first decision at HW, perhaps controversial due to his outworking Moorer, who lands the more telling blows but just not enough of them.
I think Jones beats Moorer quite convicningly at LHW... Moorer gets an awful lot of credit for knocking out a lot of "who's that?" opposition there and he never really faced top-flight contenders there... I'm not ready to pick a guy like that to beat someone as accomplished and blisteringly unorthodox as Jones at LHW... Heavyweight? I think Moorer eventually puts him out for a nap
Moorer would likely win the HW contest. The LHW one (Jones' speed & unorthodoxy vs. Moorer's power & size) would be some fight to watch unfold...
