What are your favorite rivalries or beef between two fighters? and why?
Mines are
-Chuck Liddell vs Ortiz
-Brock Lesnar vs Frank Mir
-Rashad Evans - Jones (former team mates)
-Jones vs DC, although not really a rivalry, more like a beef between two fighters. The trash talk and press conference drama and how much they hate eachother, DC crying, making PED jokes, Jones getting arrested and trolled, Twitter beef, this was just GOLD
-Conor vs Aldo I have to admit was hilarious, especially the result. I love Aldo but to have a fight that huge and travelling to like 10 different states to promote the fight and it ending in 13 seconds was so anti climatic and shocking
-Khabib vs Mcgregor. Mcgregors trash talk didn't work this time, he probably thought dissing Khabib's father would enrage Khabib and make him rush in like Aldo, instead Khabib used his anger at the perfect time, when Conor was on the ground
-Ben Askren vs Masvidal was a good beef. Nothing serious but the result was funny
-GSP Penn
