The correct answer is that you practice red zone offense against your best defense. The margin for error is much smaller in the red zone, especially on passing plays, so your offense cannot be sloppy. Our offense is sloppy. We have one of the sloppiest offenses in the SEC. Our QB is not accurate and often has poor timing with his throws. That doesn't work in the red zone. You also need a running back who can either run over people, or has the vision to pick a hole and accelerate through it. We don't have a dominant RB (even though a lot of delusional fans thought that our RB's were collectively as good as Emmitt Smith). Apparently our only option at RB is a guy coming off a serious illness who has trouble running for 3.4 yards, much less generating a cloud of dust. Maybe if we can get a couple players from the other team to generate the cloud of dust, then we could break the 3.4 yard barrier. My guess is that Muschamp practiced his sloppy offense all summer to gain yardage between the 20's to win time-of-possession, and assumed we would accidentally find the end zone once in a while. That might not have been the smartest approach. Spurrier always made sure that his offense could execute at a high level, or he replaced his players that weren't performing. With Spurrier, the backup QB's knew that they were one or two bad plays away from going in the game, so they better practice like they were going in. With Muschamp, the backup QB's know they will only go in if the QB has a serious, possibly life-threatening injury, and even then the playbook will be limited to one or two pages to keep things safe for him. So they don't need to show up for practice.
