OutinLF,
I certainly hope that is not the case amongst HS coaches? You'd think the goal would be to have as many kids move on to college as possible? Programs that send players off to play the next level are generally winning programs! In my mind, that would cement their (HS & HS Coach) reputation as a "Hall of Fame" type!
We shouldn't see any coach, in any sport, talk down to kids/students who have goals to play at the next level. A little honesty is fine, but it should be done with class and dignity IMHO!
