The 3-3-5 is the stack defense which few programs run. Davis runs a base nickel in a 4-2-5 alignment like just about everyone in the country these days. The $ position is an edge that lines up on the ball mostly.

I’m sure you are right but the defense has 3 lineman, 3 linebackers and 5 defensive backs.
I take your word for that not being a 3-3-5.
