This is like Spinks claiming he had an off-day against Tyson.
It's like eh, no, Tyson would knock you the fuck out with one arm.
Em's just a better artist, lyricist and rapper period. Jay would have to be at his very best and Em be at his "Touchdown" era to outshine him.
Plus Em had those verses laid, like I've said many times before Jay had the chance to hear them and still couldn't out-do them. And he then laid them and could hear them against Em's, so he probably thought he was better or he would of re-done them lmao.
And like class said, those verses > any verse Jay has done. They're earth-shattering.
