The Pederson for Rengifo portion seems to be separate - basically, the Dodgers don't need Pederson at this point, so get a prospect for him.
It looks like it's really Verdugo and Maeda for Betts and Price plus some money to cover part of Price's ginormous overpay of a contract. Betts' best position is also Bellinger's, so we will see what happens there. If it's really only Verdugo, that's fine. I think Verdugo will have more value before free agency than Betts, but I think Betts will be more valuable in 2020. Will he play RF or LF?
Meadows and Glasnow already were Rays, btw.
