I have a feeling most of tde's resources including creative go to Kendrick. So while we might get the cover story of Isaiah having addiction issues maybe Top offered Isaiah a check for his songs/creative input and putting his career on the back burner in order to bolster Kendrick since he was really the breakout star and they already succeeded with him anyways. Just guessing, and I know Kendrick claims he's anti ghost writer but this shyt is all entertainment. Kendrick is already basically a legend in the publics eyes and they could all eat off that for a lifetime. You telling me Isaiah Rashad made the best mixtape of the entire decade and couldn't replicate it at least once? Get real. Dude can also arguably outspit Kendrick too. He's an Insane talent.
