You can only sign 25 kids per year.
Umm...Actually its 25 per Class with limitations. Essentially, if someone in an existing class leaves before school starts (Evridge, Lopina) those scholarships can be used again and are counted against the original class they were in if given, essentially, to an existing walk on or grey shirt. Boss' scholarship, since it occurred mid year, can only be filled by counting back against the incoming class limit.
10 is a lot of players ...
What's the average for leaving in a coaching transition? How do you know its a lot?
