This is just untrue breh.
Maybe he was never revered as a solo artist, but lots of knowledgeable fans have respected his pen game and enjoyed his work on all of the Clipse albums, as well as his Re-Up Gang work, and his features with Kanye, Kendrick, etc. Push has always had lots of respect from his peers as well as fans, but just never had a solo album that really hit all the way through, despite people really liking some of his solo joints like Numbers on the Board and Alone in Vegas. I even remember people saying he got the better of Jadakiss on Lose Your Life, and that was at a time where Jada was still merking most people on features. Push has always been dope and I think most people have always wanted him to just make better solo albums, which he finally did on Daytona.
And how did Daytona flop? Sales? Streams? I mean do people really care about that these days instead of how the music was? It was a dope album that was mostly acclaimed by casual fans, diehard heads, and also critics.
The biggest criticism you can lay at Push is that he's a one-note rapper that can pretty much only do drug talk. But he does it so well that no one besides Drake stans seem to mind.
