Something I think that tends to get overlooked from the camp that just wants to keep all of our guys:
When you trade prospects for a player or player(s), that value isn’t just gone forever. If the player is truly valuable, you’ll be able to recoup value later on him, and until then, you’ll get the production from that player to help you win now. It’s essentially what the Padres may in fact be doing with Miller. They did overpay for him, but if the Padres want to get some strong value back for Miller now, they’re going to get it. Yes, you may have to take a haircut on the original value because of less control, but in some cases the production still makes the player an elite trade asset.
Look at all the guys we have given up value for that maybe we didn’t like at the time — Josh Hader and Caleb Durbin, for example, only to recoup value for the players in later trades.
