LOL OK.
I listed 4 players.
Most would imply at least 3 of those 4 players not being great assets.
So tell me which 3. Kimbrel? The best closer in baseball, under control for 4 years who was traded for a guy putting up a 20/20 season in SD? Or where other comparable closers went for top 20 prospects in baseball?
Simmons? The 4 win player who is fighting for an MVP award this year, under control for 5 years?
Gattis? The 2+ win player signed on the cheap for 4 years?
Upton? The 3-4 win player on a very cheap 1 year contract?
Please
There is a difference between a fantastic asset and a good one.
There is also a difference between whether the assets in a trade were appropriate and whether the assets obtained actually turn out.
Of the trades you mention, I think Simmons is the only one that the baseball community really questioned at all. And I don't think it was unanimous.
Of the four players you mention, Kimbrell was the best asset, IMO. And the Braves used that asset to acquire a top 100 pitcher, clear the worst contract in baseball, acquire a starting CF, another prospect, and a draft pick. Like it or not, that was a lot of value. The argument is whether they should have just eaten the Upton contract or not, but that is an entirely different question as to whether they got a good return.
Simmons and Alex Wood are two very similar propositions. They were both young and controlled and good but not great. They are both having career seasons that probably won't be repeated, but could be. Should the Braves have kept them to be slightly better in 2015, 2016, 2017, 2018, 2019? Maybe. It's hard to say. But the Braves would have still lost in the first three seasons. to me they would make good trade chips now. I wish Atlanta had them back so they could trade them again. Wood's return having been odd and unsuccessful, I wish that especially.
Gattis was not great player. He's a 30 year old catcher with reason to believe he will age poorly that already doesn't really have a competent defensive position. He was worth something and the Braves got something. That's not one I lose any sleep over whatsoever.
The Braves got a lot for a year of Justin Upton, IMO. Just as they did for a year of Heyward.
