Is Haymon going to keep all of his fights in-house?

Yes, and if other fighters want in they'll have to sign with him.

I imagine he will deal with smaller promoters maybe Goosen, Roc Nation maybe, Main events. Can't see him working with GBP or TR

yes,he wants to make money off all fighters

The answer is most likely No unless there is a title that he thinks one of his guys can steal, like Johnny Gonzalez or Andy lee. Obviously someone that's really really good and dangerous will not be welcome unless they sign with Haymon.

I think the NBC deal and the fights he has scheduled for this year are great, but is he going to do business with GBP and TR? Well is Shafer there ? If so I doubt it.
