again...the whole song was about "control" who is controlling rap..its essentially a brag song so im not sure what you expected him to go deep into... but he was on topic and creative with it....if he didnt say shyt then neither did sean or jay
...but then he came with the BET cypher which i like better
but i think i get what you saying that the song on its own wasnt enough to put kendrick on top of the game. i think it was that there was a lot leading up to it....the cosign by dre and passing the torch, gkmc...then he made it official by calling out people. so no, the song alone wasnt enough but he kinda put it on wax what had been happening in real life
