Players to the Rockies:
1B Lucas Duda
Players to the Mets:
Can you see the Rockies front office's mouth watering at the chance to snag another pitching prospect for Coors to bastardize? Me too. Rafael Montero provides the Rockies with another pitcher to throw into the mix, and (let's be honest) they were desperate enough to give Roy Oswalt a shot so they're still looking.
Another lefty reliever would take some of the load off Rex Brothers (i.e. Eric O'Flaherty and Jonny Venters) and further solidify a bullpen looking to build around Brothers, Rafael Betancourt and Matt Belisle.
Wilmer Flores provides the Rockies with another option in their infield mix which is currently comprised of Nolan Arenado and Josh Rutledge. Wilmer Flores could thrive at Coors Field, providing a boost to his borderline home run power and his plate discipline is a little better than theirs. He could provide help in either of those regards.
Now this is the tricky part. For this to go down, Todd Helton has to retire after the season. That's the only way the Rockies take our big lerch Lucas Duda because anyone's stomach would turn if they saw the drop off in outfield defense that Duda would provide opposed to Gonzalez. They'd have to stick him at 1B and watch him pop 25 over the wall at Coors.
I think this deal is fair and works out for both clubs. The Rockies get two Top 10 prospects from the Mets as well as two serviceable role players with MLB experience.
