Nominees: Jon Jones* (17-0, 1 NC) Jones' dominance in the 2010's is similar to GSP's dominance in the previous decade, especially in the way Jones improved in rematches against Alex Gustafsson and Daniel Cormier. Jones has been repeatedly caught cheating with PED's which is inexcusable. Khabib Nurmagomedov (21-0) Khabib arrived in the LW division at the right time, IMHO. He's not faced a killer's row in his UFC career. With that being said, it would be hard to think of a fighter from any time in the UFC's history that would legitimately match up with him. Conor McGregor (18-3) Conor successfully transitioned the UFC from the GSP/Lesnar era. The sport has been a little down since his departure (along with Rousey) but that speaks to his impact. McGregor introduced a new generation of fans to MMA and demonstrated new crossover celebrity heights previously thought impossible for fighters. Ronda Rousey (12-2) The only fighter who could possibly rival McGregor's star power this decade was Ronda Rousey, who has since transitioned to acting and pro wrestling, and making babies with her dullard husband (joking: after sticking up for Bret Hart when that wacko attacked him he's back in my good graces forever). Rousey literally is the reason for WMMA in the UFC and we're still reaping the rewards of that. Amanda Nunes (15-3) Her UFC career was almost derailed in 2014 when she was TKO'd by Cat Zingano, but instead Nunes flipped a switch and became the greatest WMMA fighter of all time in the span of maybe four years. Nunes has faced all of the best WMMA fighters and world champions and has absolutely wrecked them. Germaine de Randamie, who Nunes is now 2-0 against, showed the world that Nunes can bleed, but there are very few contenders lined up behind her to take advantage. Demetrious Johnson (22-3) The WEC legitimized smaller weight class fighters. DJ took that a step further, injecting himself into the conversation for best pound-for-pound fighter for several years straight. DJ never had the support of the UFC behind him, save for praise by Joe Rogan, but advanced the cause of the smaller fighters through that adversity, and continues to do so with ONE.
