Yeah, and just to put it frankly, I'm more interested in seeing what Musgrove can do in the NL. Yes, he has struggled in some similar ways, but unlike Glasnow, he's had a bit of sustained success in MLB as a starter, and I think will benefit from the move in leagues. The one thing I worry about with him is whether the Pirates approach to pitching will make him less effective, i.e., less bat-missing.
This may be simply the product of offseason mind-mush, but I think to some extent, it's an ok guess that Musgrove has a solid chance to basically be a Taillon-lite pitcher for us, in pretty short order. He's proven much less, but the elements seem to be in order, and I don't put a whole lot of emphasis on the fact that he went to the bullpen last year, because of both the division and role he was being tasked with, not to mention the Astros depth. If he can become somewhat like Taillon - and making this comparison is both an attempt at praising Musgrove and being a bit measured about where Taillon's ceiling is - then I basically think we'll be in the position of having two solid upper-middle rotation pieces, and a whole sundry of possible back-end options. That leaves us in search of an additional impact arm, and to that end, we are basically waiting on either Glasnow to put some things together, or Keller to emerge.
Given the market, I think you could make a reasonable argument that now is as good a time as any to gamble with some money for an Alex Cobb, since the strategy for this team basically boils down to trying to hang around and win key series / get a push at the right time, and then see what happens if you can make the playoffs. Bracketing the looming threat that for any WC game, you need an offense that's not going to just go completely cold, what you really need to pull that off is depth and consistency at starting pitching.
There's not much point in arguing over Cobb, because there's no chance it's happening, but we're trying to manufacture the pitching from within, and so I think in both the immediate and longer-term, giving Musgrove the first shot is probably wise. If he can be a Taillon-lite, then you at least have two pieces of the equation solved for the next little while, and Glasnow will have some opportunities, and perhaps ultimately be most useful if he can be the kind of pitcher who throws 2.2 shutdown innings at a time for a while.
