Jones never broke down the bigger man. He excelled when he was able to bully guys. I don’t think his game would translate against a big guy who can grapple like brock or Curtis Blaydes. Jon is a better grappler than a striker but him in top shape in his prime is a good 60-65 pounds less than Brock who is a high level wrestler.
Jon avoided bigger guys for a reason. The Reyes and Santos fights along with the first Gustafsson fights all made him look human. That’s why he was scared of rampage in the lead up and why he retired to avoid Tom. He’s still one of the best to ever do it but I don’t think his game would translate well to HW. He has much more of a chance against prime Brock than he would say prime JDS pre Cain though.
