Announcers used the term "muff" to differentiate it from a fumble.
If Ewers ever had possession of the ball, and then fumbled it, he would have been the only one who could have advanced it. Since he never had possession of the ball, it was a muffed snap, it was live and anybody could advance it, which Brooks did.
