I just don’t think Smith should cost that much. He’s a pretty equivalent pitcher to Justin Wilson at the time of that trade, but he has a half season less team control. And he doesn’t come with Avila. Wilson really was affordable, so Smith should be too.
Melancon was far better than Kintzler at his peak, and has gotten better results lately. I’m not a huge fan, but he’s a better fit than Chatwood. Other than Zack Cozart, I don’t think there’s another bad contract deal that remotely makes sense.
(I think rebuilding teams and those looking to follow the 2015 Cubs/2018 Braves as surprise contenders should be interested in Chatwood, by the way...so a better solution would be to convince some team of that. But I don’t think that’s likely to happen)
