There is pretty decent market on starting pitchers after the big names like Sale, Framber, Giolito, Bassitt, and Cease come off the board.
Guys that have had quality seasons in the past but have an injury, age, or poor performances
Jordan Montgomery
Frankie Montas
Tyler Anderson
Steven Matz
Tyler Mahle
Aaron Civale
Martin Perez
Jose Quintana
All these guys project under $10M for next season.
We really only have 1 guy in our rotation that we can count on in Hunter Brown. So I think you are going to need to sign at least 2 guys from the list of 2nd/3rd tier. I don't think Crane will spend for a true #2 guy. McCullers, Blubuagh, Javier, Arrighetti, France, and Ullola are all wild cards, but if healthy those guys are all capable of delivering 3-6 rotational results.
Wesneski, Blanco, Walter, and Garcia are obviously out for most if not all the season.
