Let's pretend for a few minutes that you've just been named the new general manager of your favorite team.
Congratulations on your new gig, but it's time to get down to business.

Coincidentally, every starting pitcher within the organization is scheduled to become a free agent after this season, and there's only enough money in the budget to sign one guy through 2018.
(I did warn you that we're using our imaginations here.)
Which guy would you choose to keep?
That's the mindset from which these possible, eventual aces were chosen.
We'll start out with some healthy debates over 10 teams with several viable options and close with the remaining teams for which the decision is a no-brainer for one reason or the other.
