If Tom gets reckless on a blitz against Jones he's getting KTFO by a standing elbow.
Jones has plenty of power, but his lankiness means that he has to focus on speed if he wants to be able to actually hit anybody at distance. Long limbs take more time to pivot, so when it comes to punches and kicks Jon throws almost all straight strikes - jabs; straight crosses; front, side, and back kicks. He throws some roundhouses using speed technique too (lifting the knee and snapping with almost no hip swing with extended leg). He doesn't throw power punches because they'd be way too slow to land at distance. He'd also prefer to clinch or grapple than to counterpunch, so hooks and uppercuts are largely missing. But get in range of the elbows recklessly and he'll clinch while landing the elbow full blast and you'll learn full well the power/speed combo Jon can present. Wrist control to elbow to clinch is one of Jon's signatures.
