He takes the Saban coaching tree approach. You'd almost think he coached for Saban given the secrecy. Personally, I think that's the right way to go. Since injury reports and suspensions aren't required as public knowledge, like they are in the NFL, you can just keep everything quiet until gameday. No reason to reveal anything you don't have to. Granted, the internets tend to make keeping anything hushed pretty difficult.
