A$AP Rocky is the Brooklyn Nets of rap. He's wayyyyyy bigger nationally than he is locally. When A$AP was bucking all those trends, it was flying in the face of all the locals who were still holding out hope that one of these dusty mixtape rappers would blow and while he became a big star, locally we'd rather play a Ferg track. Honestly, the lack of local love is probably why we don't view A$AP even on the level of Meek Mill & Future, let alone Kendrick /Drake/ J. Cole. In their cities, they get all the love. I can't remember when A$AP Rocky had the kind of adulation that Pop Smoke had or that A Boogie has.
And that's another thing: A$AP Rocky didn't have someone co-signing him from jump, We got conditioned to feel like if someone huge wasn't signing you or co-signing you, then you either weren't worth playing or we had to be skeptical of your come up. The mid 2000s, if Hov, Dipset, Kay Slay, 50 Cent, Fab, etc., wasn't riding for you or you weren't the next star on their label, we didn't trust you (I call it the MIMS effect; MIMS had a #1 song and all we could ask ourselves was "who's mans is this?")
