So now you criteria is not making it,but being regular starter? Guess Desmond doesn't count since he was technically picked by Expos.
Peacock made Nats roster. Others have been traded for pieces. (Norris, Ray). others are good looking prospects.
Being that most high schoolers take at least 4-5 years to make it and "Nats" first draft was 2005, you are really only going by the drafts between 05 and 08.
Hood-has chance
Hicks
Nieto (has made majors)
Smoker
Burgess
Souza (has made it)
Norris (MLB starter)
The black hole draft of 06 pre rizzo
09 was all college guys early
10 has a good prospect in Cole. Harper was essentially a high school guy but doesn't technically count
11 was all college guys
Too early to tell in guys drafted 12 or later
