By the UFC, Showtime, McGregor, and Malignaggi. And it's brilliant.
Step 1: Hire former world champion (who just so happens to work for Showtime), to be your main sparring partner.
Step 2: Leading up to sparring, have McGregor & Malignaggi throw insults at one another publicly so the anticipation grows.
Step 3: Create a storyline that McGregor's camp set Malignaggi up in 3rd world accommodations, made him fly coach, etc...and just so happened to allow photographers in the sparring sessions without Malignaggi's knowledge or consent.
Step 4: Have McGregor and Maliganaggi pose in some controversial photos that will make McGregortards cream their orange and green skivvies.
Step 5: "Leak" photo's to the public.
Step 6: Finish off the storyline by having Malignaggi unexpectedly storm out of camp because McGregor is unprofessional and disrespectful. Malignaggi's a pussy now that got his ass kicked by McGregor.
Step 7: Profit by shattering PPV numbers.
Step 8: Set up Malignaggi vs McGregor in MSG for Conor's second boxing match because although he couldn't beat Mayweather, he can surely beat the guy he toyed with in sparring & embarrassed so badly he stormed out of training camp.
Nobody is actually believing this shit, right? Wrong. I see tons of McGregortards and casuals on other forums & social media doing just that. McGregor, Floyd, Malignaggi, Showtime, and the UFC are laughing their asses off all the way to the bank.
