How am I exaggerating? I said Bones is bigger in terms of frame, height and reach, which is all true. The point being that Jones isn't really smaller than Brock, and likely won't have much of a size advantage outside of weight, which won't mean much if he can't muscle Jones around or lay on top of him. Again, Cain is smaller and handled Brock. It's not all about brute size. I wouldnt' be surprised if Jones is as strong in the octagon as Brock. It's one of the things DC (who has fought HWs before) commented on after their first fight. That Jones was way stronger than he ever imagined.
Saying "if Brock is the one hitting those shots" is pretty meaningless. The reason those shots were landing were not because of raw power. They were because of DC's hand speed and technique. things Brock has zero of.
Bones looked plenty sharp in there against a world class fighter like DC after such a long layoff. If you want to talk about recency, Brock, meanwhile, is 40 and looked mediocre in his only fight in years against Mark Hunt, a fight where he was juiced to the gills to boot.
What size? Hunt is only a heavyweight because of his gut. He's smaller than even DC otherwise.
And Jones has done zero for people to question his chin. He's taken shots from some heavy handed dudes and rarely ever been fazed.
