Ole Miss coach Houston Nutt is playing a little guessing game heading into the Rebels’ biggest game of the season.

He’s closed down all of practice this week to the media. The first four periods of practice are usually open to the media through the week. It’s the first time he’s done this since coming to Ole Miss, reports David Brandt of The Jackson Clarion-Ledger.

Players and coaches are still available for interviews after practice, but it does make you wonder.

I’ve always been part of the crowd that thinks whether a team’s practice is open or closed is vastly overrated.

There just aren’t a lot of secrets anymore, and how many of us in the media (and that includes me) can sit there and watch a practice from all the way across the field and discern if a team is putting in a different blitz or changing up its pass protections.

If you’re trying to hide an injury, that’s one thing. The same goes for switching around personnel on special teams or trying a few new wrinkles on offense.

I guess we’ll find out Saturday if Nutt has a few surprises in store for the Crimson Tide.
