In this system, S's are extremely important. Both sides have to drop, creep, rotate from half to post, understand when they are a COP (Contain Outside Player), when they are the fit in C, when they are a robber, and when they are C3 or C4. Among other responsibilities and rules.
We do need studs at that spot as well. I'd rather have that position with 8's & 9's and find a nickel amongst our other options that can be 8's or 9's at that spot than turn our S's from 9's to 7's.
But I understand the appeal and allure of the nickel position needing to be a stud in this system. This system needs excellent secondary players or extremely smart secondary players to function at a high level (both is, of course, ideal).
Hussey? Or purely safety?
