3) Be aggressive in the trade market
Having an exemplary farm system has done more for the Dodgers than just produce young talent, it's also given them the pieces needed to make blockbuster trades. Current Dodgers obtained via trade include Chris Taylor, Tyler Glasnow, and one of the best players in baseball, Mookie Betts.
Friedman hasn't been afraid to turn young pieces into players that were more of a sure thing. The Mets are emphasizing player development and getting younger, but that shouldn't keep David Stearns from pulling the trigger if the right deal presents itself.
Every season, there are always big names available for the right price. Whether they come from teams that have fallen short of expectations, teams that are looking to shed payroll, or teams that just don't know what they have, Stearns needs to be aggressive in trying to bring the right guys to New York.
Right at this moment, there are impact players rumored to be available via trade. Corbin Burnes of the Brewers, Masataka Yoshida of the Red Sox, Jonathan India of the Reds, Randy Arozarena of the Rays, and the White Sox trio of Dylan Cease, Luis Robert, and Eloy Jimenez are all names that have gone through the rumor mill. Every one of these players is an All-Star-caliber talent.
This isn't to say that Stearns should necessarily make a play for any of the above names. Rather, it's to point out that big trades are out there if the Mets ever decide to get aggressive. The Dodgers have shown that such a strategy can pay big dividends, and if the Mets want to get on their level, they should follow suit.
