True EZ, but you have to remember that throwing your arm out in the minors is similar to throwing it out in college. There is no guarantee you are going to get called up in the first 3-4 years. I can think of very few direct from HS athletes who have gone straight into pitching after being drafted recently. Most take at least 6-12 months, many much longer. Then you deal with the athletes who get stuck in the minors forever and see their lives waste away as they blow their signing bonuses and have to live on a teacher's salary. I'm a teacher, it's not easy folks!
The Yankees youngest active pitcher is listed with a D.o.B. Jun 24, 1986
The Red Sox are worse on the active. Even on the 40-man roster, the Sox have one from 1987.
Then look what happens when a qualified pitcher comes out of Nebraska and plays for the Yankees organization.
Go browse through MLB draft history on ESPN and check out the first-round pitchers and you won't see many with career stats up yet.
