I don't know how involved Floyd will be in TMT battle league, but if anything, he should know this. Although battle rap and boxing are different, there are certain parallels that work for both forms of entertainment. His promotional company was always built on homegrown talent. It took them years to develop a roster that could challenge for world championships. He never signed established talent.
50 Cent came into boxing with SMS promotion, tried to make this big splash by signing established talent, and failed. Roc Nation did the exact same thing and failed. That approach has never worked in boxing. The established promoters like Tank Rank, recruit guys from the amateur system, and develop them into stars. Of course some work out, and some don't. They may occasionally sign an established guy if it makes sense, like a Tyson Fury.
Do you remember how hot Spit Dat Heat and We Go Hard were at one point? It was because they had their own talent. I think We Go Hard fell off when they started using established talent that were just looking to collect a check. They never really regained their momentum back after that. Bullpen was a decent platform because they had their own roster.
There is value in exclusivity.
