Conor McGregor could hang it up if he loses at UFC 264 and here is why

#2. Conor McGregor just can't keep up anymore

Even for a man of Conor McGregor's talent, the UFC lightweight division is not easy to rule.

After Khabib's retirement, the division became wide open. The crown is now up for grabs by anyone, with several elite contenders vying for Charles Oliveira's belt.

Congrats to Olivera on becoming the 11th UFC lightweight champion. Wonder who Twelve is...

Justin Gaethje, Michael Chandler, Beneil Dariush, Tony Ferguson and Conor McGregor's current foe, who most believe is the best lightweight in the world, Dustin Poirier.

The welterweight division is not going to get any better for Conor McGregor either. The contenders keep getting bigger, stronger, and a stylistic nightmare for McGregor's skill-set.

#1. Conor McGregor has nothing left to prove

For as much bashing Conor McGregor receives for his recent, it's hard to find many resumes that can match his.

Conor McGregor was the first simultaneous two-division champion in UFC history.

He won the featherweight belt after knocking out the legendary Jose Aldo in 13 seconds at UFC 194. He then beat Eddie Alvarez by TKO in the second round, winning the lightweight title in the process.

The Irishman also has knockout wins across three UFC divisions.

'The Notorious' is the biggest superstar MMA has ever seen. He has headlined seven of the top 10 most PPV buys in UFC history.

He has also been lucky to achieve these impressive feats without acquiring too much damage, a rarity in professional MMA.
