There's no guarantee any of their prospects fill the void. The only notable players from their system on the team are Judge and Sevy.I understand there's levels to it and it's worth it for Soto. The teams that are vying for him also have major holes elsewhere. If the Yankees for example only needed Soto, no questions asked, but they got pitching issues, starting and bullpen. Their SS sucks and they'd be theoretically be trading any hope of a replacement for IKF.
The Mets on the other hand need to grab the city by the throat. Soto on the Mets would cancel out not getting A-Rod in 2000.
I remember the hype around Phil Hughes, Ian Kennedy, Jesus Montero, Justus Sheffield, Miguel Andujar, Gleybar Torres, Gary Sanchez, Jorge Mateo.
I would be shocked if Volpe or Dominguez wind up even close to the player Soto is and likely will be for the next decade. That guy is built for New York and Yankee Stadium.
