Luda would’ve popped no matter where he signed imo. Again, I don’t think most rap fans know they even have a relationship.
Its not like 50/Em, Em/Dre, To a lesser extent Boosie & Webbie to UGK, etc.
There are known cases of labels fumbling projects from artists who later went on to major success.
T.I. is an example. His label fumbled I'm Serious. He got dropped, regrouped and became a superstar on another label.
Saying that Luda would have blown up regardless, and without the Def Jam muscle and leverage is speculation.
Was never a fan of either rapper but one of Luda's lines on Stomp alludes to what I posted here, and ethered Tip.
"Your deals keep getting fukked up, my contract practices abstinence!"
