he had no choice.
Drake been pushing in on his territory so instead of honestly taking the opportunity to work with Drake more, he realized he had to swallow his pride and recognize greatness.
Notice, they even said Jay peeped game early and let Drake get his shine.
Not even a Drake fan, but I def noticed this, and I KNOW it's hurting Kanye. I think him bringing Kendrick on his tour was a last effort shot...
And Jay just does his usual thing.... Jay don't like half the people he has worked with, but he knows how to play the game.
