Jones legacy can not be tarnished with your words. He has fought a lot of legit guys. If mayweather trained with phil davis hed still get destroyed because he just doesnt have enough takedown defense/wrestling to compete with wrestlers who are focused on only taking him down. I know you like to make it seem like any boxer who boxed his whole life can just train wrestling for a few months and destroy the entire mma circuit but you really underestimate these guys and definately need more knowledge as it concerns fighting. Gus has also won grappling tournaments where there are real killers man. Thats not something you can just pick up at mcdonalds in a few months These guys are striking and grappling on a daily basis for years of their lives. I cant ask you to have more understanding because i guess you feel boxers are true fighters, but, MMA is a different animal with less rules to protect boxers from the natural flow of a fight.
When it comes to BJJ you have a point about grappling, what I'm talking about is wrestling
but anyways, Jon Jones was caught by Vitor and literally powered his way out of it with brute strength
its no guys in MMA that excel at MMA
as in being technical sound at all facets of the sport, so a boxer with the right trainers can easily adapt
he doesn't need to excel at grappling just needs to train on stopping the take downs and keeping the fight on its feet
look at Rampage, he isn't an elite BJJ, he ain't an elitle wrestler either even thought thats how he kinda started
his boxing is severely limited but he was knocking out top guys, he went his entire MMA career without being submitted, until he was overpowered and over matched
by the bigger stronger Jones, who was really just deboing dudes with brute strength
Its dudes in the hood with better hands than Jon Jones, they just don't know how to do armbars and triangle chokes, which is stuff that can be learned
