17 would seem about right. Assuming every freshman redshirts (not necessarily the case but a high % do) 85 scholarships divided by 5 years comes out to 17 players per year. Sure attrition such as; players transferring, quitting school, or in the case of Lane declaring for the draft makes it so not all players stay 5 years. But we take on, or at least in the past have, a lot of transfers so that offsets some of that.
