Everyone does this against Belfry. Belfry typically only has one SE so 9 in the box is basically automatic.. if you put a single CB and have a lone Safety that is 9 that by default will be in the box.

Truth be told the best defense against Belfry is a team who can emulate what Central does. Play your LB'ers at standard depth where they can read and react. Play your CB off several yards. Use your speed to shut down the outside and react quick inside after spacing out enough that linemen can't block multiple defenders. The issue is most teams don't have the speed or athletes to pull this off.

I have always said the worst thing you can do is put everyone up in the box against Belfry. That creates a dangerous situation with only one level to break before they take a long run in for a touch down. You have to depend on linebacker play. Another thing that helps is if your defensive lineman hold up those tackles and keep them off your linebackers.
