If I was him I would go camp out at Alabama for a year or two as an analyst, but Id be shocked if Saban would want someone with a heavy analytics philosophy on his support staff.
He'll get calls from P5 programs as a linebackers coach just because of his perceived SFL ties. I think he'll leave the state and ACC. I could see a mid tier SEC school like South Carolina/Auburn.
He should honestly try to move to off-field and try to become an AD down the road, I think that better suits his skill set than on-field coaching.
