#3. MJF wears Conor McGregor's iconic suit, but a different version

Floyd Mayweather Jr. v Conor McGregor World Press Tour - Toronto

Conor McGregor took the combat sports world by storm by donning a now-iconic black suit during the media tour of the Floyd Mayweather fight. The suit had pinstripe designs made of the phrase 'F*** YOU' and was extremely on brand with McGregor's entire demeanor during the build-up to the match.

Maxwell Jacob Friedman, better known as MJF, wore a similar suit on last night's AEW Dynamite. While it could be mistaken for a tribute at first glance, it was anything but. Upon a closer look, MJF's suit had the words 'BETTER THAN YOU' pinstriped instead, subtly hinting that he considers himself superior to the UFC megastar.

What further cements the idea is the pair's recent Twitter exchange a few days back. After MJF called Paddy Pimblett a "Dollar store Conor McGregor," the Irishman fired back defending himself and 'The Baddy'. In response, MJF called McGregor a "roided up leprechaun" along with other profanities.

#2. The sun and the moon are of the same size, and Joe Rogan is scared to debate me about it - Bryce Mitchell

Bryce Mitchell wants to debate Joe Rogan on Flat Earth Theory

Bryce Mitchell has once again called out Joe Rogan for a debate over Flat Earth Theory. 'Thug Nasty' said in an exclusive interview with Sportskeeda MMA last month that he wants to debate Rogan about the concept on the JRE podcast and prove him wrong "in front of as many people as possible."

Mitchell spoke on the matter once again on the Champ and The Tramp podcast recently and told the host, Roger Mathews, that he believes the UFC commentator is too "scared" to debate him on the topic:

"No man, I think he's a little bit scared, brother... People act like I have the burden of proof. Go outside and look, do you see the Earth spinning at thousand miles an hour? Do you see the Big Bang?... The sun is small. It's closer than they're saying it is. It is the exact same size as the moon, because they're counterpart. The sun and the moon are the exact same size in the sky."

Listen to Bryce Mitchell below:

In a 2017 episode of JRE, Rogan chatted with American physicist Lawrence Krause on Flat Earth Theory and chided those who believed in it.

#1. Kevin Holland calls out UFC for not giving everyone "a fair chance"

Kevin Holland doesn't feel UFC treats everyone the same

Kevin Holland hinted that his decision to retire from MMA came from a place of feeling discriminated against. Answering a reporter's question ahead of his UFC Fight Night bout against Stephen Thompson, Holland shed some light on his call to hang up the gloves:

"I was serious as hell. Super serious. It's still on the table. If I wake up Sunday morning after beating 'Wonderboy' and you guys have [Khamzat] Chimaev fighting for the 185-pound world title when he has never won a fight at (1)85 in the top 15, I'm retired. I understand business is business, but favoritism is favoritism."

He also slammed the UFC for the addition of Raul Rosas Jr. and Bo Nickal to the UFC 4 roster when they are yet to make their debuts in the promotion.
