I know this info is somewhere but I haven't found it yet.

In 2003 there were about 1480 players taken in the Draft.

Any breakdown as to how many were from DI, DII, DII NAIA, JC and HS?

Play every game as if it were your last

Not sure of the numbers but it goes most high school next dI then jc.

Combed the 2003 draft and filter out the following for RHP's only.
