#4. Conor McGregor's fall from the rankings
Conor McGregor, who once reigned supreme in one of the most stacked divisions in the global MMA landscape, is inching closer to the bottom of the barrel.
Currently ranked No. 9 in the UFC's official lightweight rankings, Conor McGregor has suffered a tangible fall from grace. A serious comeback seems highly unlikely.
What's more, Conor McGregor does not even feature in the UFC's pound-for-pound rankings. It's something that has perhaps affected McGregor's stock in the eyes of the fans.
Although the Crumlin native is still a threat in the octagon, many argue that his overall marketability and ability to sell tickets is what prompted his retention in the top-10 of the UFC's lightweight rankings.
#3. Conor McGregor's tendency to throw hands outside the octagon
At a time when Conor McGregor is in dire need of his fans' support, his actions outside the octagon are only working to drive them away. Lately, McGregor has built up a negative reputation. Having indulged in a series of brawls with non-fighters, McGregor is no longer seen as just a brash trash-talker, but as a seriously unhinged individual.
Conor McGregor has attacked his fair share of non-fighters; however, one of the most infamous instances involved an elderly man called Desmond Keogh at a pub - The Marble Arch - in Dublin. He subsequently acquired the pub and banned Keogh and the journalist who broke the story from entering. He also renamed it The Black Forge Inn.
One instance that could have exacted a heavy toll on Conor and the McGregor clan was when he attacked an individual linked to the Kinahan cartel in Ireland.
Conor McGregor also got into it at this year's MTV VMAs with popular musician Machine Gun Kelly, attracting the wrath of fans and pundits all over the world.
His most recent scuffle involved Italian DJ Francesco Facchinetti. The DJ found himself nursing some serious injuries after getting decked by the Irishman at the St. Regis hotel in Rome.
