Ken Rosenthal posted a story earlier that the Mets, Nationals and Rays could have been involved in a three player trade that would have sent SS Ian Desmond to the Mets, Zobrist to the Nationals and Mets prospects to the Rays. The Rays would have received Noah Syndergaard and an unknown other prospect in the Mets system.
Desmond would have been a tremendous upgrade at shortstop, but Desmond is also a free agent next year. A top tier pitching prospect, plus an additional top prospect would have been a fairly steep price for Desmond. At best the Mets would get to sign Desmond to an expensive contract and at worst they would have received a prospect.
I want the Mets to upgrade at shortstop, although Wally Backman has calmed me slightly about Flores starting. But the price in that trade, plus possibly losing Desmond at the end of the season is too steep. I rather give up four top tier prospects and pay a ton of money for Tulo knowing that he would be under contract for a while.
