Texas Rangers Organization Discussion

I am now working on the St. Louis Cardinals Top 20 list and comments for the book. The next team is the Texas Rangers, to be followed by the Philadelphia Phillies, Detroit Tigers, Arizona Diamondbacks, and the Tampa Bay Rays.

Use this thread to discuss the Rangers organization. Is there enough talent left in this farm system to continue producing playoff teams, either providing fodder for trades or players for direct promotion? As usual, feel free to point out any interesting sleepers who might otherwise fly under the radar.
