The Nominees Are: Nate Diaz vs. Conor McGregor 2, UFC 202, 08/16 Robbie Lawler vs. Rory MacDonald 2, UFC 189, 07/15 Jon Jones vs. Alexander Gustafsson 1, UFC 165, 10/13 Shogun Rua vs. Dan Henderson 1, UFC 139, 11/11 Anderson Silva vs. Chael Sonnen 1, UFC 117, 08/10
Lawler vs MacDonald 2 is my favorite fight ever. I don't know that I have seen a better fight in all of my life. I will say Alvarez vs Chandler 1 in Bellator was probably my 2nd favorite fight of the decade.
The drama and brutality of Lawler/MacDonald 2 is a once-in-a-lifetime thing. It's the Hagler-Hearns of MMA. Clear choice for me.
