Rappers going from WACK to DOPE? Which rappers improved the most?

[The Devil's Advocate]

2chainz and BOB can be considered most improved.....they weren't horrible to begin with, but they have came a long way

listening to old ludacris albums... 2 chainz actually dumbed it down and admitted it

his freestyle on rap city back in the day....

jay-z..and im talkin bout the early, "skippity-be-bop" fast rappin jay..shyt was wack to me

"you say never you run if eva you come its neva u run so fast in ya life to neva have won" dude was trash

you do know almost half those raps were off the top right?? i wouldn't take '13 jay over reasonable doubt jay tho

Chris Kelly went from wack to dope.

Didn't work out for him though.
