Arizona Diamondbacks organization discussion

I am now working on the Cleveland Indians Top 20 Prospects list for 2017. The next team in line is the Arizona Diamondbacks, to be followed by the New York Yankees, the Washington Nationals, the Houston Astros, the St. Louis Cardinals, and the Tampa Bay Rays.

Use this thread to discuss the Arizona Diamondbacks organization. Potential points for discussion include, but are certainly not limited to,

***The Diamondbacks finished with an extremely disappointing 69-93 record, a performance that cost GM Dave Stewart his job. How quickly can the new front office rebuild? Does the entire edifice need to be torn down, or can this team be improved more rapidly?

***Should Zack Greinke be traded, assuming you can unload some of the huge contract?

***What do you expect from new trade acquisition Taijuan Walker?

***What do you expect from Archie Bradley? Can he harness his stuff once and for all?

***Brandon Drury: how good will this guy be at age 27? Is he someone to commit to long-term?

***What’s your draft strategy for 2017?

***As always, feel free to discuss sleepers or anything else Diamondbacks-oriented.
