Kilroy: when you use the term "selective," what type of school are you referring? For example, the University of San Diego has an average for admitted students which baseball players do not need to meet. There is way more latitude to admit a player to USD, then say, MIT.
USD is a fine school; but is not MIT.
Coaches are not shy about laying out the required scores and grades; the player being recruited will be told whether he makes the academic cut or, if not, what he needs to do (e.g., retake SAT).
