Francis7, the comparison you make doesn't work. In the case of D1s especially, there has been recruiting, a coach has at some point said he thought you were good enough, or would/could become good enough. Or else why would you have gone to that school? So the coaches are at best careless and heartless (yeah, business, I get it). And once there, a lot of kids work really hard and are not entitled, and still don't make the grade.
@BaseballMOM05 I agree with you completely, have seen it happen. It's brutal and unfair. Really the only thing that can be said, as is said over and over, is, don't be a walk-on, if they don't give you scholarship money, go elsewhere. But even then...
