Atlanta Braves organization discussion

I am now working on the Minnesota Twins Top 20 Prospects for 2015 list. The next team in line is the Atlanta Braves, to be followed by the Kansas City Royals, San Francisco Giants, Baltimore Orioles, and Chicago Cubs.

Use this thread to discuss the Atlanta Braves farm system. Possible points of discussion can include, but are certainly not limited to:

***The major league club finished 79-83, costing general manager Frank Wren his job. Do you think this team can return to contention in 2015, and if so, what young players would you be willing to rely on?

***True or False: Tommy La Stella can be a long-term regular second baseman. Why or why not?

***How much do you believe, or not believe, in Christian Bethancourt and his bat? Will he always be a defense-first guy?

***The Braves still seem to have a knack for pitching, but what can be done to improve the development of young hitters? Or do you think improvements in that department are even necessary?

***As always, feel free to discuss any sleepers you like.
