I can't speak for everyone here but for me that's not it at all. I love Isan Diaz. I think he's a heck of a prospect. If the Marlins are going to value him the same as Dubon, I'll trade Dubon. But since they're not, I'd rather keep Hiura. Diaz is not being suggested in trades as a 'throw-in', he's being suggested for the opposite reason, he has substantial value, and it's going to take a substantial value offer to land Christian Yelich or other top trade target. So it makes total sense to deal from a position where you already have a higher rated prospect of similar age at the same position. We won 86 games last year and we have a heck of a 40 man roster crunch coming up after 2018. So naturally there is some discussion about using prospects to upgrade the MLB roster now. Guys like Brinson, Ortiz, Diaz, Harrison, etc, are involved in the discussion because these are the types of prospects you're going to have to give up to land guys like Yelich and Archer. If that's too high of a price for some people to pay, sure, I get it, but other people have good reasons for wanting to go the other way with it that are by no means crazy. If all you're willing to offer up is the next tier guys like Dubon, Cody Ponce and Trey Supak, you're not going to land the kind of fish we're talking about. Very well said.
