When talking Alonso versus Soto in trade and then for an extension, to me the issue comes in how long Alonso will want. If he will sign a 5 year or at most 6yr deal extending him is fine. If he wants 8-10 years I am not interested. Where with Soto you can go 12 years and know, barring injury, at least the next 8, and probably 10, should be very good.
Alonso does make some sense, especially if you don’t have to deal Morel or any of the top 10 prospects for him and even more so if the Cubs really feel Morel can handle 3rd. But I don’t want him in his late 30’’s.
This is also based on Alonso costing far less in salary and acquisition costs than Soto.
