My Overall Thoughts
It feels like we have enough depth & quality depth here that we wouldn't necessarily be looking to supplement too much in free agency - especially if we are paying to supplement our rotation, which means more impact starter quality arms in the bullpen.
Hopefully they can find a few diamond-in-the-rough types (& less rough-on-the-diamond types) as depth this year has definitely been a concern, but I don't really see them exploring the high end of the relief pitcher market...unless they find a deal they like & move on from Jansen.
