I get annoyed with all the arguments about how to define an “ace,” but in that spirit, I don’t see what you’re describing as a “rebuild” if all you’re trading is Polanco, Kepler, Maeda, Gray and Pagan.
And given that you’d be trading several of these at a point of low value, why bother? You’re not going to get much now, and thus not much less if you do it later. Conversely, you might actually get more later if any of them have a good first half.
Plus, if they have a good first half, they’ve also potentially addressed an existing need. And if so, the team may actually be in the race. And if any them has had a good first half, but the team isn’t in the race, there’s probably a higher level of urgency on the part of trade partners than there is now. And at that point, they can trade several of them and open the Falvey Levine Buffet to also include Gallo and others among the offerings.
So add me to the “no” column.
