Baltimore had the same problem for a long time. I cant tell you how many top 15 pitchers we've drafted and how many have panned out? NONE. There is hope for Gausman, Harvey and Bundy...but...I give more credit to getting the right pitching coach in there. Since we brought in Dave Wallace, our staff has been great.
I don't know if I would completely blame Bridich for all of the woes. There have been a few decent young players to come through the system during his time in that role. Pitching in Colorado is just going to be tough...period.
Gray had a decent season at Tulsa and has a few things to tweak, but he should be a regular in the rotation by 2016 at the latest. Just have to find and develop a few more like him
