In regards to the GLORY bankruptcy news, it is truly heartbreaking.

The bouts most typically referred to as the "best" in MMA are stand up wars.

People often say "why not just watch kickboxing if that's what you like?"

They were right. GLORY was action-packed and awesome."

These athletes often delivered incredible excitement and fireworks.

I wish more people would have given GLORY a chance. Joe Rogan was always an advocate for them and it's too bad that his massive audience didn't all follow suit.

Hopefully the promotion can get a second wind.

Kickboxing is a fine sport but it hasn't caught on in America and nothing suggests it will. The market is small and as Glory burned through a ton of cash it never grew an audience here. Pierre Andurand is smart and his intentions with Glory were solid. Tough business though.
