I mean, Kyle Hendricks is your 5th starter right now. Do you want him to become your 4th?
I had kinda hoped that, beyond normal leveling out of variance, the real pen upgrade would be a healthy/fully stretched out rotation. We saw the difference between April (terrible pen) to May (8th in fWAR) that just pitching a normal amount of innings makes a huge difference. And then I figured that Steele/Shota/Jameson/Wicks/Assad would let you push Brown to the pen, you'd have Horton not that far away, Almonte/Merryweather/Adbert have to come back at some point. But clearly just not going to happen for us.
