Thank you for the compliment. I'm never sure how to answer questions like this, because I'm not a Cardinals fan so I don't have that like/hope to see any specific player. I'll cover whoever and try to tell their story or explain how they ended up as Cardinals. I said Corey Seager earlier in the chat, and that's not because it's a move I'd "like to see." It's just more of a move that makes the most sense for what the Cardinals are missing from their current roster. Lefthanded bat stands out. I am happy to pass along who makes sense in these roles, who the Cardinals see in these roles or what they should do with these roles. But my personal wishes aren't a factor, really ever.
A) They should approach the DH as a bonus and license to go out and find the best possible player/fit at any position and work from there. DeJong at DH or part of a DH makes a lot of sense for the current structure of the team. But using the DH to get Arenado days, Goldschmidt days, O'Neill days of rest is really the best use of the DH, and again gives them the flexibility to focus on the best bat they can get and then arrange the DH around that.
B) Nootbaar has earned it. Burleson will get a long look. Plummer can make a case.
C) Really unclear at this point. Three-way race between Sosa, DeJong, and outside options. A lot of this will really turn around the cost of the SS market and if the Cardinals want to be a big player in it, or if they see someone's value sliding and want to pounce.
