From an old head let me tell you the downfall of Big Daddy Kane was one of the saddest things ever in hip hop
There were several reasons. The biggest one was that trash azz 3rrd album. He said he was beefin with his label and just put something out there hoping to get released. Kane was an elite level MC but he also had an urge to be an R&B dude. Hip hop wasn't really feelin that. Also its the early 90's and hip hop is going through its pro-black, socially active phase. It was ATCQ, De La, Poor Righteous Teachers, Brand Nubian and some others time to shine. New MC's coming out had an updated style of rhyming. It was curious as to why Rakim disappeared back then. Dropped Don't Sweat the Technique in '92 and then vanished for 5 years. Probably was a good thing. Seems like rap went through a lot of changes just from 1990 to the mid '90's. Probably a good thing to sit back and let things settle. So he maintained his legendary name.
If Kane had been in the biz today, it would have been a different result. There was no internet then, which today is helping rappers maintain their careers, even after dropping a dud. And the hip hop audience was more cutthroat then. Hard to recover after dropping a bad album back then.
Make no mistake though - Big Daddy Kane is one of the illest MC's in the history of rap music!! He's on my 80's Mt. Rushmore.
