Then don't do the deal. You should never, ever allow another team to devalue the assets you're trading. The Dodgers reportedly love Wood, so you base the negotiations on what he is, not what he could be down the line.
And if they won't do that, then you back out. Again, we were not in a position of desperation; we did not have to make a trade. The Dodgers were in a much more desperate position than us, especially when Hamels and Price came off the market. We got diminished value for Wood, which is an indictment on the FO in this trade. It is not a defense.
Value is what someone is willing to pay. We appear to think we know value but the Braves clearly felt that this was there value. Maybe they are wrong but people pretending to be experts on this board is too much to take right now.
Like I've said before, nobody would have thought Hanson/JJ/Beachy would have had no value after four years it happens quicklym
