I see nothing wrong with going without a huddle or with a fast tempo, but when it reaches a point of exploiting the rules to where you run plays without the refs in position to make calls or the defense being able to get lined up, it mocks the essence of the game (which, to me, is two teams lined up against one another with an equal chance of making a play).
The baseball equivalent would be a pitcher throwing a pitch before the batter can get into the batter's box. Or a basketball team inbounding the ball and scoring while the other team is still in a timeout huddle or replacing a fouled-out player. In those sports, the umpire or referee determined when everything is set and when play can begin. In football, the refs--and not the offense--should make that determination as well. Otherwise, it becomes a mockery.
