I'll echo some of the comments about Woody above. He looks fantastic right now, though its only been 5-6 starts. With some of the younger guys likely to have some growing pains at some point, it would be really beneficial to have that steady veteran mentor who can also take the ball in the deciding game of a playoff series.
No idea what it would take, but Woody does have that long-term "Franchise player" pedigree that Braun, Yelich, and other long term signs have had.
Given the underwhelming return (atleast in the moment) for Hader, Burnes, and Williams, maybe we try to run it back next year (to defend our WS win of course) with Woody & Peralta, and let the young guns (Miz, Priester, Henderson, Patrick) continue to gel, with Ashby, Hall, Gasser, and Myers continuing their bullpen/spot start roles.
Do we try to get anything done with Turang, Frelick (who both have a couple years of solid performance under their belt), and atleast see what it would take to lock in some of the younger rookies?
