Jones at Middleweight? Was near unstoppable, and he was unstoppable at Middleweight. Jones only had trouble at Light Heavyweight(if Delvalle is considered trouble for one round)

But Jones only showed weakness aftr moving back down in weight.

if this is 100 percent Jones at Middleweight(his prime wasn't until Super Middleweight) then he may be near unstoppable but Hagler would be more experienced.
