Cassidy - right around the time Jay-Z retired and NY didn't have many to take his place, niggas was saying Cassidy was the future and that on the mic no one could stop him. Welp that came to an end when he got hemmed up. His debut album even went gold.
Drake - when he first came out with So Far Gone (to this day I still haven't heard the album in full), upon the release of TML niggas was tryna say his coming was that of a young 50 Cent circa 2003 SMMFH. I never thought he woulda been around this long. I remember there were threads and polls with niggas arguing going back and forth of what Drake would sell. Now Drake is the most hated on next to Jay-Z, Kanye West, 50 Cent on the IC.
Cosign on Saigon - Niggas were repping it like it was going to save NY,
Lil Wayne - Around 2008/2009 he could do no wrong he was killing the mixtapes had threads in his honour, etc. Soon as he sold a mil in the first week and dropped A Millie it was as if the IC got turned upside down.
