Lord Jamar's recommendation on Grafh doing Southern hip hop vs Desiigner is exactly why other coasts laugh at New York. He damn near killed his credibility with that garbage-ass recommendation.
Basically: "we don't fukk with the South unless it's someone from New York who we like. and then it's OK if he/she bites because he/she's showing that it's an easy style to pull off."
Meanwhile, the NY imitator is 9 times out of 10 doing a TERRIBLE job at it.
