Jones has eaten flush shots from the former heavyweight champ without flinching, has statistically outstruck every fighter he's ever faced (yes even the first Gus fight and the Santos fight too) and has never even been seriously rocked, let alone knocked down or KOed in 27 fights. 44 year old Silva was giving Izzy problems in the clinch and was able to land clean whenever he actually bothered to fight instead of doing his wingchun pantomime backed up against the cage; until Jon is pushing 40 himself Izzy has no hope of being competitive against him. Dude is barely a year removed from almost losing to Marvin Vettori; weight classes exist for a very real reason and there are plenty of fun, exciting, competitively justifiable fights for him at the weightclass he just won the title in half an hour ago that don't involve arbitrarily forcing him up another one to fight arguably the best fighter to ever live
