Not to me. Roy sure has a fragile mandible. But if he gets KOd, It won't be because he has a glassier jaw than Maccarinelli, It'll be because he's ridicioulusly old and washed up for boxing.
:roflatsch Jones was savagely KOed by Glen Johnson who has no power at 175. None. Do you even watch Boxing? Jones has an awful Glass Jaw all the evidence is out there.
I've seen %90 of RJJ fights, thank you. And I never said Roy doesn't have a glass jaw, I said I don't think his chin is weaker than Maccarinelli's which I don't.
If you swung a sledgehammer at Seth Mitchell's jaw and gathered up all the shattered glass from it and piled it up, then you did the same with the glass gathered up from Maccarinelli's, Deontay Wilder's, David Price's, James Kirkland's, Amir Khan's, and Audley Harrison's glass mandibles and added it to the pile in would still pale into insignificance compared to the mountain of glass you would be able to gather up from Roy's mandible section if you shattered it with a sledgehammer.
There's not another human being on the planet those punches would've even wobbled, let alone knocked them senseless or sparked them out cold.
In 26 years, 70 fights, spent fighting, on average FAR higher standard of boxers than Enzo has, Roy has been stopped 4 times. Enzo in his 46 fights has been stopped 7 times. I dont think Roy is necessarily the chinny one in this fight. He is, however, far older, and far, far....FAR more shot.
Actually, Jones is definitely susceptible to being knocked out in this fight. However, Enzo Mac's Chin is actually worse than Roy's, as hard as that may be for some to fathom or accept. And everyone knows that current Jones has very, very limited punch resistance. Maccarinell actually has the weaker Chin, as shocking as that may be, Serge. This is the unbiased (and unfortunate) truth. Assess their careers and watch as much footage of both fighters as you can. Having said this, either one of them could stop the other in this fight.
