Friedman was well aware that the Braves coveted Hector Olivera. They'd scouted him heavily and tried to sign him before the Dodgers blew them out of the water with a huge signing bonus. Now the Braves get their guy, minus the signing bonus, at the cost of one of their best pitchers and a guy who could be a better Dee Gordon. Could Olivera step right in at third base or second base for the Braves? Absolutely. So far, in his roughly 100 minor league plate appearances, he's looked fine. But he has a shaky medical history, and he's 30. He's no spring chicken. While he doesn't have to be a perennial all-star for this trade to not look like a stinker, it's puzzling you'd give up a strong starter like Wood.
Dave Cameron of FanGraphs has pointed out that Wood is comparable to David Price and Cole Hamels, just without the track record. Price is a rental and Hamels is now with the Rangers. Hamels is expensive. Price, again, is a rental. Wood is probably earning the league minimum (under $600K) next year and has three years of arbitration ahead. Combined he'll be about the same price as roughly a season and a half of Price or Hamels going forward. Yes, they had to deal a pick in the process, but it was the Marlins' pick, and they had to eat $20+ million of signing bonus payments to Olivera. That seems worth Alex Wood and the possibility that Peraza is going to be a starting caliber infielder.
The Dodgers had to take advantage of their massive financial resources, but it's money they were already spending anyway. They actually save money here. It's hard to say where Michael Morse fits on the Dodgers, but he'll probably be flipped, too - Morse is nowhere as bad as his numbers this season would suggest.
So is Andrew Friedman and Co. a company of mad baseball geniuses?. It hasn't even been a full season, but the reallocation of resources is going very well so far., especially going forward
