I think the new staff can sell the sizzle (while they are undefeated) and they don't necessarily need 9 wins in season 1 to continue strong recruiting in years 2 and 3. Start and upward trend and sell playing time.
They likely have built relationships with kids in the junior and even soph classes. More importantly, they have relations with high school coaches in our NY, NJ and Atlantic region that should work indefinitely. Sure, it will take the transition from the SEC brand to SU and Upstate. Lots of reason to be optimistic that it is not a flash in the pan.
