I don’t think Fulmer’s struggles change any of the calculus. Ultimately we need to convert three of Kopech, Lopez, Giolito, Hansen, Dunning, & Cease into top of the rotation starters. Rodon will be in the mix for a while as well. We can always sign a veteran mid-rotation starter if needed to backup. And if we can’t develop a #5 starter between the guys I listed and all our other pitching depth, then we have larger problems at play.
Therefore, definitely take BPA at #4 so unless Mize suddenly falls, that player should hopefully be a position player.
