Depends if you want to go full re-build. I wonder if the Cubbies would want Jose (depends when they want to go for it). They may want to use Starlin to get pitching, but a deal based on Starlin and Alcantara would be interesting (probably more pieces involved). Gives us our MIF for the next 6 years. Lets us trade Reyes at the same time.
For the Cubs it gives them a nice veteran bat to anchor the middle of the lineup with Rizzo. They don't have an IF spot for Alcantara anyway and lets them bring up Russell. They need a CF, but having Soler and Bautista in the OF corners is pretty appealing.
