Conor McGregor’s decline from a promising spot on MMA’s Mount Rushmore to being notoriously inactive has been hard, but watching him launch a dolly at the window of a bus, I thought, “Conor is 2007 Britney.”

Seriously, brace for impact.

In 2007, Britney just lost it. She shaved her head and took her rage out at the paparazzi by damaging a photographer’s car with an umbrella. That led to a rough couple of years for the pop star, but she has recovered.

Conor might’ve not shaved his head just yet, but someone definitely “held his beer” as he took it a step further and used a dolly as his weapon of choice. The target, a bus holding UFC fighters inside the Barclays Center loading dock.

Why? Well, Conor got word last week that his loyal friend and teammate had a verbal confrontation that led to him being surrounded by the headliner of the UFC PPV event and his team at a hotel lobby.

Now, I get it. You want to step in and defend your friend and make it fair. But not many would fly all the way from Dublin, Ireland, with 15 to 20 friends on your private jet and your dime to Brooklyn, New York, to do something about it.

Then again, most of us aren’t Scrooge McDuck rich. So, Conor arrived at the loading dock with his posse and started to attack the bus like a hooligan because the fighter and his team that approached Conor’s teammate happened to be inside.

This infamously led to Conor racing over to a nearby dolly, picking it up and launching it into a bus window as if it were part of a strength & conditioning exercise.

Conor, like Britney, had a massive meltdown. Some would argue he overreacted, while others would say he blacked out. Either way, he damaged a bus and could’ve killed or seriously injured someone.

Now, New York was the last state to legalize MMA because of the perceptions of fighters being violent hoodlums. Years ago, Senator John McCain denounced the UFC as “human cockfighting.” The UFC has worked long and hard to change that image with better officiating, rules, smarter training and implementing the national anti-doping organization, USADA, for the integrity of the sport.

What does it say about the UFC when the face of the company and the entire sport acts out of control and injures others along the way?

He always makes a statement of some kind to bring publicity and eyeballs onto any fight card or press conference he’s involved in. Two years ago, when he fought regularly, McGregor came off as clever, strategically marketing himself with outlandish statements and predictions.

But there’s nothing clever or marketable about trespassing through Barclays Center with a rowdy posse, causing mayhem by slinging objects at a bus filled with other fighters and UFC personnel. When the dolly shattered the window, he injured two fighters, causing them and their opponents to be off the card.

This might’ve been an extravagant, over-the-top fight promotion, but McGregor hasn’t fought in two years and avoided defending both belts, which he is stripped of now.

“This is the last stunt on Earth that we’d ever pull,” UFC President Dana White said on ESPN. “This is embarrassing for the sport and obviously for the UFC. This is the furthest thing from a stunt. This is bad.”

McGregor’s acts have grown tiresome for a year now. He often instigates obnoxious Twitter-wars and makes cryptic posts, rather than actively fighting. It’s upsetting and hard to watch as a fan of the sport and of Conor.

Time will tell if Conor comes back as the Conor-of-old or worse than he has been, but one thing is for certain. He has a loyal fanbase and he is must-see talent. I’ll be watching his next fight, whether it be in the octagon, boxing ring or with the law.
