When the you mentioned the greatest Mixed Martial Artist ever it is almost impossible not to mention his name. He is still the rightful Pound 4 Pound king of MMA and he has never really been defeated in his MMA career. Jon Jones has been running through his opponents left from right since becoming UFC Champion. But run ins with the law and drug use may continue to tarnish his legacy. Anyone in the Light Heavyweight division that was champion or was on a roll, Jon made easy work if them. He even out wrestled current champion and former olympic wrestler Daniel Cormier to roll in a Unanimous decision victory in their last encounter. Jon Jones is a once in a lifetime athlete and could be the Michael Jordan of this sport but his bad decisions continue to tarnish his legacy. Jon stormed into the UFC with an impressive record of 6-0 and fought very unorthodox using his length and reach to his advantage. Soon he later showed his superior grappling skills and got better with every fight. Who can't remember that crazy spinning elbow he landed on Stephan Bonnar? Almost every move by Jon was a highlight reel performance. But a Disqualification loss is the only thing that haunts his record. Though, fans in others in MMA feel that it was a round call because even though the blows were illegal that wasn't the reason Matt Hamill (the only person to defeat Jon Jones) but for a torn shoulder he received in the fight. President of the UFC Dana White has said that he wishes to get that removed off Jones record due to bad referee calling but it still remains there. When Jon defeated Shogun Rua in 2011, he took the world by storm defeating every opponent in impressive fashion. He almost made it look easy to some especially beating former champions in the UFC. He defeated the likes of Rashad Evans, Rampage Jackson, and Lyoto MachiDa and many more. He has he most title defenses in UFC Light Heavyweight Championship history and is a two time champion without ever losing the title. There have been rumors of him going to Heavyweight and eventually challenging for the title but nothing has ever came about. Jon will hopefully have a rematch against Daniel Cormier for the title Jon never lost. Cormier has been impressive since Jon has been away defeating Alexander Gustoffson and Anthony Johnson twice. Daniel Cormier and Jon Jones were supposed to rematch at UFC 200 but USADA flagged Jon for doping and the Jon was replaced by Anderson Silva. Hopefully we'll be able to see Jon get it together or will Cormier be able to finally end their rivalry and hand Jon his first loss?
