OK. I think I've got it.
At NSD 2016, we were at 84, including one for Ratliffe, and held one for the kid who eventually chose Cal. If he had signed with us which seemed possible at.the time, we'd have been at 85.
From the NSD 84, we then lost 6: Ratliffe, Griffin, Whitley to medical, kicked off John Marvin in Spring and later CJ Leggett, and also lost Whitehead.
84-6=78 +Muns =79
(gojackets.com Eligibility says 78 because they left off Simmons who sat out the Spring, but not Merriweather who was just shifted down a class with RS).
So, we're looking at a class of 6+13 (Srs) or 19 next year, plus any attrition.
We have the space to sign 20. We can switch a walk on ship if we need to....so if its 19 now; we should sign 20 and leverage a walkon ship if we need to
