He's been on multiple tracks with Cole on it and he never drops a verse, he just sings the hook and Cole raps. (Forbidden Fruit, American Dream, Under The Sun)I highly doubt that Kendrick is at all “afraid” to hop on a track Cole it just seems like he really just don’t fukk with either Cole or Drake like that. Kendrick comes off as avery solitary type of artist. He doesn’t even collab with Black Hippy nowadays.
He don't wanna rap with Cole.
