I think the assumption that he missed out on anything is off base. He was locked in for 70k for the Surf battle, but that fell through. He didn't start ASKING anyone to book him. The fans constantly ask him, John John called him out and said he can get the sponsors, now we are here.
Once you stop looking at it like he desperately needs bread, you'll see he's just putting a business proposition out there. It's safe to say he will be promoting a new musical project next year under Busta's Conglomerate. Battling multiple times in a year would help him promote the project. Also, multiple battles means that his naysayers can't discredit everything he's ever done if he has a rough night. And I'm sure there are even more reasons beyond that, because dude is all about mapping things out.
You're calling him dumb when he's managed his career better than damn near anyone in battle rap. Especially when you consider he doesn't translate all that well to people that don't follow battle rap. Your favorite battle rappers would be pretty excited to get advice from Mook. You have guys out here like Math, Rex, Verb, Daylyt, etc. that are in limbo. They want to move on from battle rap, but they don't have the means to do so. Mook is chilling.
