Why not? Certain judgment calls just aren't reviewable. I don't actually know if you can or can't review that, but it seems like the kind of thing they keep unreviewable Are you talking about the Cutler sneak? They didn't rule forward progress was stopped. The side judge ran right along the sideline indicating he just didn't get in. It was reviewable. No, UM thinks you can review to see when forward progress was stopped, not just where. So, hypothetically, even if he hadn't gotten into the endzone, they could rule that he was "down" before he fumbled because his forward progress had been stopped for long enough.
