Lester makes sense. With our "Big 3," we have upside. What we needed was a durable innings eater that gives us a chance every 5th day. Lester fits that bill. I like Ross as the 5th guy.
This is a team with some holes, but there's a path to contention. I think we're going to very much evaluate in the first half and potentially make deadline moves as needed. If our Big 3 aren't healthy/good, then we're sellers regardless. If they're good, then you look at adding a bat. I'm ok with giving guys like Kieboom, Garcia, and Stevenson their opportunities and seeing what we have in them. It shouldn't be impossible to find a bat as needed later.
I don't expect much else other than a decent lefty bullpen addition and then just some bench/depth pieces. 1st half developments will determine if we "go for it" or not.
