#2 Conor McGregor vs Eddie Alvarez - UFC 205
Conor McGregor had the chance to make history at UFC 205 by becoming the first-ever double champion. The featherweight king went to Lightweight to headline Madison Square Garden in a historic card and historic night.
McGregor absolutely decimated Eddie Alvarez from start to finish, taking less than two rounds to finish the Lightweight champion at the time. McGregor was the favourite but he put on an absolute masterclass of a performance on the biggest stage, proving why he's worlds apart as a competitor.

#1 TJ Dillashaw vs Renan Barao - UFC 173
This was the most unexpectedly dominant performance ever. Renan Barao was on a 32-fight win streak (you read that right). He won and defended the Interim UFC Bantamweight Championship before getting promoted to undisputed champion.
Few people gave Dillashaw a chance, but what took place in their first fight was five rounds of absolute destruction by Dillashaw. He would finish him by round five and Barao would never be the same again.
He got another crack at Dillashaw, but it turned out to be an equally lopsided affair like the first time, with Dillashaw finishing him by round four. After that, Barao went on a major skid, never being the same again.
