I disagree but not vehemently. I mean obviously Khabib's competitive history is that of sambo, combat sambo, and grappling, but he is most definitely a wrestler too. Sambo practitioners are pretty much all wrestlers (or judokas, or kickboxers) who decided at some point in their martial arts journey to compete in sambo. Its a sport made up of athletes from other sports. Also, of all the training Khabib has done throughout his career, he has trained at the wrestling club headed by World champ, Olympic medalist Sazid Sazhidov as much as anywhere else. Not to mention all the time he spent/spends in the wrestling room at AKA with DC, Cain, Shawn Bunch, Jamil Kelly, etc.
