I just wanted to update some previous FanPosts I made on drafting by Ranger GMs and Best overall Ranger Draft Picks. I haven't gone through to update all the previous GMs, but I did go through JDs stuff since he suffered the most from not having enough time for players to accumulate WAR. All WAR used is bWAR.
So in 2 years, JD vaults up to 4th or 5th on the list ( http://www.lonestarball.com/2011/2/18/2000756/ranger-drafts-by-gm ), behind Robinson, Grieve, and Melvin. I suppose their is a chance Hart made up some ground and got to the top 4, but I didn't take the time to run his picks.
None of JD's guys have done enough to crack the top 31 Ranger Draft picks of all time yet. http://www.lonestarball.com/2011/2/4/1974572/top-31-flavors-of-ranger-draft-picks
