This week's Sports Illustrated has a sidebar article, (not yet on-line), on trading players for prospects. They provide some examples. They may have been cherry-picking but here is their list:
Mark Teixeira and Ron Mahay for
Jarrod Saltalamacchia, Elvis Andrus, Neftali Feliz, Matt Harrison and Beau Jones
CC Sabathia for
Matt Laporta, Rob Byrson, Zach Jackson and Michael Brantley
Cliff Lee for
Carlos Carrasco, Jason Knapp, Lou Marson and Jason Donald
Roy Oswalt for
JA Happ, Anthony Gose and Jonathan Villar
Carlos Beltran for
Zach Wheeler
Zack Grenke for
Jean Segura, Johnny Hellweg and Ariel Pena
Matt Garza for
Carl Edwards, Justin Grimm, Mike Olt and Neil Ramirez
David Price and Austin Jackson for
Drew Smyly, Willy Adams and Nick Franklin
I'm not going to look up all those guys right now. You can find them here, (assuming they all made the majors):

You're trading above average major leaguers for prospects. I remember when the Mets went from winning 100 game sin 1986 and 1988 to losing 100 game sin 1993. They had a lot of trades like this: something for nothing. Just two years ago the Mets seemed like a coming team with a great young pitching staffs. All they needed to was to build a good starting line-up and it seemed to me that they had done that this year, (when everyone was healthy).
Now the Mets are dumping salary and they are doing it to get pitching prospects, which emans that they don't think the golden rotation of Harvey, Wheeler, DeGrom, Syndergaard and Matz is ever going to happen. Meanwhile the message to the team and the fans is to forget this year and maybe the next couple of years. I've always thought dumping salary was more about the owner's pocketbook rather than the team's future.
That was a short era. I wonder what Beau Jones is doing these days.
