Things happen quickly in the world of mixed martial arts, where one mistake can see a champion lose everything he or she has built in a matter of seconds. 

Lightweight champion Khabib Nurmagomedov (27-0) experienced that reality in a completely different way on Saturday thanks to his ill-fated decision just seconds after his UFC 229 win over Conor McGregor to leap the Octagon wall and unleash a flying dropkick on his opponent's team. 

While the MMA world awaits both the UFC and Nevada State Athletic Commission's ruling on Nurmagomedov's future following the ugly melee he personally triggered, the narrative that was understandably overshadowed by his reckless behavior is still worthy of mentioning: the native of Russia just might be the best fighter in the world.

Long a charter member of the "eye-test club" due to how often injury and happenstance prevented him from proving himself against the 155-pound division's elite (including UFC's four failed attempts to book a Tony Ferguson fight), Nurmagomedov provided visual proof at just how truly dominant his grappling and ground-and-pound skills can be. 

Nurmagomedov didn't just dominate McGregor (21-4) en route to a fourth-round submission via rear-naked choke, he appeared to mentally crush the brash Irish star who was returning from a two-year layoff and had given his Russian opponent more than enough reason to following a crass and acrimonious promotion. 

Most surprisingly, Nurmagomedov also fared well on his feet in the stand-up against McGregor, including a crushing right hand that briefly dropped one of the UFC's most talented finishers. 

As the most dominant fighter in the sport's deepest and most dangerous division, Nurmagomedov's future could bring an assortment of fun and interesting matchups provided his actions on Saturday don't force the powers that be to throw the book at him. Either way, Nurmagomedov is operating at a level of self-belief and calculated violence inside the cage that makes it difficult to imagine anyone solving him.
