DaBaby holds himself in very high regard.
In fact, the NC spitter thinks he's so good that other top rappers are afraid to work with him.
“Best mf rapper & I’m on ALLLAT sh*t these n*ggas LIE about,” Dababy stunted on social. “I’m him frfr. If a n*gga ain’t tryna work with the real thang he SCARED. The best supposed to compete w/ the best These n*ggas just TALK like they like dat SHUUUUT UP.”
There may be other reasons other rappers won't work with him besides DaBaby's level of skill.
Assuming this whole premise isn't just cap, they may be scared off by his declared 300K per feature price tag -- which nobody on earth is going to pay.
They may also be worried about his history of beating and shooting people, sometimes to death, and always getting away with it.
