From future Hall of Famers to fledgling duds, the D-Backs have seen it all in their short existence.
When MLB announced plans to expand the National and American Leagues to 16 and 14 teams, respectively, Joe Garagiola Jr. (March 1995-Aug. 2005) was named the first Arizona GM.
Garagiola was succeeded by Bob Gebhard, who held the position for all of two-and-a-half months from Aug. to Oct. of 2005. Gebhard, in turn, was followed by current San Diego Padres GM Josh Byrnes (Oct. 2005-July 2010) and current Los Angeles Angels of Anaheim GM Jerry Dipoto (July 2010-Sept. 2010).
Current GM Kevin Towers took over for the interim Dipoto in late Sept. of 2010 to complete the five-man all-time Diamondbacks GM roster.
During their various tenures, the GMs conducted trades, signed free agents, designated players for assignment, presided over the annual arbitration periods and simply cut players from the squad. Garagiola's regime additionally participated in the 1997 expansion draft.
A great number of these moves were successful—they gave us stars like Luis Gonzalez, Randy Johnson and Ian Kennedy—but some moves never quite panned out.
Some transactions even sacrificed successful players for other big leaguers or prospects that haven't upheld their ends of the bargain.
Now, in retrospect, this is a list of 10 players the Arizona Diamondbacks never should have gotten rid of.
