4. P R.A. Dickey, C Josh Thole, and C Mike Nickeas to Toronto Blue Jays for C John Buck, C Travis d’Arnaud, P Noah Syndergaard, and OF Wuilmer Beccera (December, 2012)

This one is the steal of Sandy’s tenure as GM.

Parlaying the Cy Young winner (Dickey) into a haul of well-regarded prospects (d’Arnaud, Syndergaard) seemed like a good move at the time. Now it is one of the best trades in Mets history.

In half a decade, especially if the Mets have won a World Series, this deal will likely be even more important to team history.
