I think the 4 yr guaranteed schollys is a little bit of a misnomer. Sure it sounds great, but you can still get around it. Sit a kid down after 2-3 years and basically tell him "it doesn't look like you are going to see the field here. We'll keep you around, but if you ever want to play, you should consider transferring." I'm guessing a lot of kids will get that message and either transfer or quit.
