Next year definitely. He would be potentially competing with Drake, Kanye, Dr Dre etc etc tho.
If he releases before Sep 30th he’ll be competing against Nas, Tyler, and J.Cole.
I don’t list Kanye because he’ll probably submit in the Contemporary Christian category again.
I don’t list Drake because I doubt Drake will even submit his album this year after he trashed the Grammy’s last year in support of The Weeknd.
Kendrick will sweep the Rap categories. The only real debate will be if he finally captures an AOTY win.
