If Shaw struggles at AAA then what?
There's just nothing out there in terms of 2b FA. I don't see a world where you're getting back a starting 2b for Nico, so I just don't believe they are getting Nico's value back.
There it is, you don't believe in the core.
Does it make sense to address a black hole at 3b with a good player just to turnaround and trade a good low cost player at 2b and create another black hole? I don't see that at all. You can add the big bat at RF or DH this offseason without having to move your valuable 2b. You have money to spend, and a large prospect stash to move to address the remaining needs - Big bat, catcher, SP (Maybe), and BP.
