I keep saying the BJ savings allowed us to trade for Touki, and everyone seems to keep ignoring that. We absolutely did not need the BJ savings to add JJ, Norris, and Beckham, so that's not what it allowed us to do. Plus, it gave us room to turn CJ's 2017 money into 2016 money, so we now have both BJ's and CJ's savings to use in 2017. Obviously we will have to wait to see how we use it, but we still have savings there.
Second, the Padres' return basically centers around two guys. Allen and Asuaje aren't bad pieces, but they also mean little. A 24-year-old who OPS'd about .700 in AA and an 8th-round draft pick. Allen has potential, but his ceiling isn't high.
So the trade centers around Guerra and Margot...both definitely good prospects, but Guerra would have been redundant for us with Albies (and Albies is better), and Margot and Wisler are pretty similar in value at the time of the trades, plus Wisler will play a big role for us starting this year. So while you can look at our return as Wisler/pick/money and it doesn't look great, you can also look at it as Wisler/Riley/Touki and it suddenly looks better than what the Red Sox gave up.
And again, you simply can't take one bad deal and assume we could have gotten the same kind of deal. The Red Sox undoubtedly overpaid for Kimbrel; there is no guarantee at all that anyone was willing to offer something similar even if we had kept BJ, especially considering that the current Red Sox FO is new.
