Resources are limited though and we should not waste them on lateral moves. Seager costs us $18M next year and money that could be used towards RF. The prospects you’re talking about giving up could be two major pieces for a legit TOR starter this offseason.
Personally, if a guy like DeGrom isn’t available this coming offseason, I’d rather just keep Kopech & Madrigal, sign someone like Stroman to a 4/$80M deal, and acquire the best stop-gap RF that can buy us a year until hopefully a Cespedes or Colas is ready (assuming we sign one of them).
