As much as I hate to say it, Pac would have been
by now and his career would have similar to how career 50 is today, he would have burned way too many bridges with all those beefs he had.
He would most likely would be broke too, basically Ja Rule status in the game, he probably would be still dropping albums today but no one would be checking for them in the masses like they was with AEOM, 7 Day Theory, etc.
Biggie probably would have a decent Career Until getting ethered by Nas and later on Dipset, Camron would have clowned his appearance in a song and Jim Jones would have knocked Lil Cease kufi off
He would be hurting financially as well, Faith most likely would have divorced him and got him for Child Support money for that kid they had, he would also had to pay Child Support for his baby mama before he got famous.
