Understood, but J is talking about if Dilla had a chance to have his career play out without passing early, Kanye would have been surpassed/would have been nerfed at some point. Not a reach to me, especially since he ended up doing it to himself.. and Dilla was just as versatile with his production discography without being as "big" as Kanye. If only Dilla was alive to make this easy. There is no guarantee Kanye takes the same trajectory had Dilla lived.
In the era that Kanye West blew up as a producer, it was in the middle of The Neptunes/Timbaland dominance, the beginning of the crunk wave, Dre was pretty dominant himself. I don't see what Dilla could've done or was doing that was going to stop Kanye. Even onnthe innovative side, Timbaland was still sampling crazy sounds and songs from other parts of the world
