The top 100 list is nice, but solid quality depth is as important, all those arms they've stockpiled the last couple years in AA and AAA, need a couple to fill out the bullpen. This is where that scouting/coaching nexus comes in, anyone can identify a 100 MPH FB, where you earn your money is identifying the pitcher with mechanics that are fixable and the mindset to do the work to fix them. Same with hitters, raw power is easy to scout, plate discipline, swing mechanics, eye to hand coordination, reaction time, and again, coachability. We've seen too many hitters die in the upper end of the system after a good start.
Skepticism is deserved, but for a couple decades they wouldn't even acknowledge they had a problem, probably b/c they had one hot streak in the 90s (Rollins, Howard, etc) and got complacent. The current team has few homegrown players, Stott, Bohm, Rojas. Nola, Ranger. Some prospects went in trades, most haven't panned out. O'Hoppe for Marsh, Mead for Sanchez, Maton/Vierling for Soto, Cleavinger for Alvarado, Miller for Marte, and Sanchez/Alfaro for JT.
