It's already too late. Rendon loses value, daily. Several teams will want to upgrade third base in an attempt to make a run. This needs to be done now.
J.B. Bukauskas and Garrett Stubbs should be in our farm system. That was what the Astros offered for half a season of bad Bryce Harper.
Rendon should get you Jesus Sanchez and Lucius Fox from the Rays.
Kimbrel brought in Margot and other decent prospects. Given what Kimbrel is going to cost in money, Doolittle, if healthy, gets at least that. The Braves might be desperate enough to cough up Pache and another prospect.
Eaton will bring back something. Maybe to the Padres for Xavier Edward's?
Gomes will get a low level prospect. Maybe Suzuki too.
