MLB exec: D-Backs made 'worst trade' ever

The Atlanta Braves will likely pen a thankful Christmas card to the Arizona Diamondbacks for almost single-handedly restocking their farm system.

Having already pried away the D-Backs' 2014 first-round pick, Touki Toussaint, in June, Atlanta netted an overwhelming haul of prospects from Arizona on Tuesday in exchange for right-hander Shelby Miller.

Braves general manager John Coppolella has taken heat over the last several months for trading away several veteran players, but the package of right-hander Aaron Blair, outfielder Ender Inciarte, and 2015 first overall pick Dansby Swanson for Miller has those around baseball applauding the return, and ripping the Diamondbacks' front office.

Here are the best reactions from the deal:

"Grand slam for the Braves." - Unidentified executive told Ken Rosenthal, FOX Sports.

"That's a helluva return for the Braves. I didn't like idea of trading Miller, but for that? Yeah, tough to argue after they got that package." - David O'Brien, Atlanta Journal Constitution

"Worst trade I've ever seen." - Unidentified executive told Rosenthal.

"I haven't seen Braves officials this excited about a trade in more than a decade. They view this as a pivot point in the rebuild." - Mark Bowman, MLB.com

"Can't wait to see who the Diamondbacks pick for the Braves in the 2016 draft." - Keith Law, ESPN

"Holy crap for Atlanta." - Unidentified executive told Rosenthal.

"I wonder if Zack Greinke is going to see this trade and ask to void his deal." - David Cameron, Fangraphs

"Rival execs in awe of the package of players Atlanta got from Arizona. But D-Backs got what they want: They're serious contenders in 2016." - Buster Olney, ESPN
