None of those guys were ever top 10 in the system, or even close to it. My question was how many of AA's top prospects had busted. Nobody is ever going to be perfect or even close to perfect in the draft, but that isn't part of equation here. The original discussion was about the likelihood in "Norris, Sanchez, Osuna, Castro, Foley, Smoral" all "crashing and burning". None of the draft prospects you guys mentioned ever got to that stature before busting.
Every time an AA pitching prospect has gotten to that level, he's either been traded for a valuable MLB piece, or he's made the roster for a prolonged period of time. The only exceptions are Deck McGuire and Kyle Drabek (who may still have something to give as a reliever).
That isn't to say that all of those guys are going to pan out, there's a near-impossible likelihood of that happening. I just don't think that there's need to take the traditionally pessimistic approach to the arms in this system, because that same system has seen a ton of success in recent years.
Edit: North was able to word it a lot more eloquently than I did.
