These battle rappers claim to be cool outside of the event, especially cool and having to utmost for Smack, Beasley, etc.
I'd like to believe they respect the platform enough, so Mook could've easily pointed it out to Smack like "yo, check Brizz before I do, he's doing too much right now".
All of this put a dent on URL's reputation, relationships with investors, booking venues, etc. It is in the best interest for EVERYONE to act accordingly and professional at all times. Fighting in/out of venues is bad for business, period.
