Jon Jones is in a sport where he has to do everything. Regardless he still won the fight. If he was in there with a top boxer. Someone whos hands outclasses his, their grappling probably does not outclass his which is when they will be taken down and submitted or pounded while they're on their back. This is MMA, not boxing. Jon Jones does not have the hands of a professional boxer but hes strong enough Everywhere and physical dominant enough to put it together well. These are the qualities of champions. You dont see a flabby n sick champions and if you do, they wont be the champ long.
You Kimbo Slice comment, I dont think that proves how much of a joke MMA is. If anything it legitimizes it. It shows that when you bring a fighter into his weakness and in the case of the Kimbo fight, that was grappling, its a whole different ball game. Im sure Ray was working takdown defense but obviously, when you're not used to it, its difficult to defend. In Mercer vs Sylvia, Sylvia stood in front of a boxer trying to prove a point and felt the hand of god.
Jon Jones another man with a good wrestling base. Some people are just freaks of nature and catch onto disciplines faster than others and it has everything to do with being able to do everything well while others are only able to do some things well. Not everyone has these gifts and being a boxer doesnt give you a special inate ability to become a great grappler just like being a great grappler does not give you an inate ability to be a good striker. There are plently of dudes that are nice on the mat but cant put it together in the Octogon when facing people that are good at everything. By age 18 Tyson was already considered a future heavy weight champion by the way he was wrecking everyone.
I get it though. Cats like you wont be satisfied with any pro boxer getting in the ring unless his name is Floyd Mayweather, Manny Paquioa or some other cat in the top ten. You're convinced boxing is the best and cant give respect where its due. It is what it is.
