Other items to consider about Walk Ons
1 - The number of kids coach invites out for fall? 50 or 35?
2 - I beleive the numer of kids under scholarships (max) is 27 for D1. That means there are at least 8 kids there without scholarship money - ie walk ons.
3 - What are the other tangibles that your son brings to the table? Pitcher, LH power hitter, etc.
4 - Who is offering? RC, HC or HS coach saying he can get you a walk on?
Just things to consider. If you do go that route MAKE SURE THAT SCHOOL IS WHERE HE WANTS TO BE. I'm following several kids that have walk ons. Some are just now getting play time soph year. Some didn't make spring roster and are looking for other ocolleges already and others committed to schools thinking he has a spot but has no idea if coach will invite 35 or 55 out for tryouts when fall starts.
My Logic..
HOPE for the best, PLAN for the worse, and something in the middle should happen!
