What's weak about it? He only talked facts
Nas did fall off- before Stillmatic everyone saw him as a guy who started strong with the first 2 albums then was on a steady decline after
That's not what Jay said though. Jay said Nas ONLY hot album was Illmatic. A lot of media critics and "real hip hop" snobs said he sold out with IWW, I Am and Nastradamus and Jay leaned into that fabrication...which is ironic because Jay went in the same commercial direction as Nas if not even more commercial. For some reason he never got the same accusations of selling out, but that's probably because Illmatic was so highly regarded.
Nas was a fantasy thug rapper
And Jay isn't?

MC Serch was up in Nas publishing
Serch himself has said this isn't true...
"keep talking and I'll tell everyone how I had sex with your bm while you were still with her"
All Nas could say was Jay Z has big lips (what's wrong with that Nas) and Jay wanted Nas on some songs
The whole Carmen angle didn't work out too well for Jay lol...
And you know damn well Ether has more to it than that. Ether pointed out how Jay was a Nas obsessive who kept Nas name up in his rhymes along with Biggie's lyrics. Those are the real facts.
