Jones vrs. Povetkin in Moscow would sell pretty well I think. Revenge!@ Jones vrs. anyone in the heavyweight division is an interesting fight, actually.
They should never lift his ban. In almost any other sport it's 3 strikes and you're out, while in boxing you can get away with a small slap on the wrist.
On the other hand, sadly, pretty much every athlete uses PEDs, and the athletes with the right money and trainers get the best PEDs. Jones got busted because DK had him fighting in the cruiserweight division and he can't make weight, so he needed PEDs to cut weight. This is pretty much the substance of his case. He's claiming that if he was a heavyweight then he wouldn't be a drug cheat, relative to other heavyweights.
You can already write out that scenario. Jones beats Kayode, but gets caught for the 4th time, and on steroids this time because he doesn't use durectics to mask them. Fight gets ruled a NC and Kayode is re-undefeated for the 3rd time :!:
