Manny wanted Zo in the same capacity but that never was going to happen.
My take is Mario convinced Zo to come back as a favor to him but it was never going to be for an extended period of time
The CFB GM role appears to be morphing into more of an admin/chief of staff position in comparison to something Zo would typically do.
Brandon Harris (former LSU player) is 28 and just got elevated into the same role this week at Texas.
