A casual glance at the reaction to the announcement of Conor McGregor’s rematch with Nate Diaz would suggest MMA fans are in clover.

But dig a little deeper and you’ll find plenty are asking: is it time UFC got over its obsession with McGregor?

McGregor vs Nate Diaz 2? UFC needs to get over McGregor, he's a bust.

The Irishman will again take on Diaz at welterweight at UFC 200 – UFC supremo Dana White wanted him to drop back down to 145 pounds or fight Diaz at 155 – while Jose Aldo and Frankie Edgar contest an interim belt as his absence from the featherweight division continues.

This seems to be exactly what McGregor wanted – but is it what the fans wanted? And is it what’s best for UFC?

Does anyone even wanna see Diaz/McGregor again?

is there anyone who actually wants to see mcgregor diaz 2?

Don't really see the point of Diaz McGregor 2 like #UFC #UFC200 #mma

Many fans feel this is simply the wrong fight for McGregor.

The 27-year-old was literally punching above his weight when he stepped up to 170 pounds earlier this month to take on Diaz when Rafael dos Anjos pulled out of their lightweight bout.

Clearly McGregor feels he the need to prove himself in this new eight class – according to White he was “obsessed” with getting a rematch at 170.

Conor McGregor really thinks he's Stallone in Rocky III/IV. Next thing you're gonna see him running beach sprints w Carl Weathers. #UFC200

But many people feel he won’t be able to prove himself because he simply isn’t a welterweight.

If you still think Conor McGregor can beat Nate Diaz you are confused and probably not even a real McGregor fan

Conor McGregor is letting his pride get in the way of common sense taking the rematch with Nate Diaz….don't see how he wins it…

Some think McGregor hasn’t even proved himself at featherweight – he won his one title fight at the weight in 13 seconds against Aldo, and immediately set his sights on going up a weight or two.

Certainly the Irishman’s status as the sport’s biggest star is based as much on his gift for hyping himself up as it is on his achievements inside the octagon.

Before Ronda Rousey’s shock loss to Holly Holm at UFC 193, White believed the former women’s bantamweight champion was the biggest draw in combat sports.

Now that accolade surely belongs to McGregor – but because of his accelerated rise through the sport, the manner of his win over Aldo and his talent for self-promotion, question marks remain.

I'm not sure why everyone is saying Diaz beating McGregor is an upset. McGregor is overrated and Diaz is so underrated

I am still ecstatic that mcgregor lost #overrated

What, then, does he or UFC have to gain from the Diaz rematch?

Aside from anything else, the match-up leads to the bizarre spectacle of having Aldo and Edgar going for an interim title at a weight he has abandoned on the undercard of his own scrap against Diaz.

I really don't care to see Diaz beat up on McGregor again. . . Make McGregor defend his belt. ??

— Jenn (@_jnovs) March 31, 2016

Yo the Diaz McGregor rematch is at 170? Why won't Conor just defend his belt ?

— mitchell lovett iii (@mitchjlovett) March 31, 2016

This is something that has really got under the skin of a lot of UFC fans.

If McGregor won’t defend his featherweight title, shouldn’t he vacate it? It seems disrespectful to have two fighters of the class of Aldo and Edgar going for an interim crown.

Also the @UFC is now a joke. McGregor vs Diaz 2 AT THE SAME TIME as Aldo & Edgar fight for his interim belt. Shambles. A JOKE. #UFC200

— Spamfish (@Spamfish) March 31, 2016

There's no reason for an interim title apart from trying to put the hype back on McGregor if he wins

— Vitamin C (@FIONNxVEG) March 31, 2016

What does it say about the sport?

And what does it say about the power McGregor has that he is seemingly able to get whatever fight he wants?

@MMAjunkie …who's the boss of the UFC ??? Connor McGregor ?…

— JUNIOR (@JRzHD) March 31, 2016

Interim belt with a healthy, active champ. How bad does McGregor have to be beat to stop the McGregor show. This feels like WWE ?

— Munique Sidhu (@UFC_Obsessed) March 31, 2016

BTW, shows how much power McGregor still has that he convinced UFC to do the fight at 170. The winner (Diaz) wanted it at 155, but nope.

— Mike Chiappetta MMA (@MikeChiappetta) March 31, 2016

Fans have been left with the impression that it’s all about the money.

And whether that’s true or not, the cynics certainly don’t have to look far for ammunition to back up their argument.

At first I thought Conor McGregor was good for MMA, but now it's clear that he's destroying it. Greed destroyed boxing too. #UFC200

— Chane Steiner (@chanesteiner) March 31, 2016

One thing’s for sure though – this is a fight that leaves nowhere to hide, either for McGregor or his critics.

Lose, and his image will be severely tainted – he will forever be seen as an Icarus character who did not know his own limits.

Win and he will justify the hype once and for all.
