well here's one for you too....i'm in hurry up mode in the 4th clock is stopped at the beginning of the play, here's what happens
1. complete a pass
2. get tackled
3. play took 6 seconds to happen
4. next play starts with 30 seconds taken off the clock
conclusion, there isn't a true hurry up offense, since a hurry up offense is usually a no-huddle offense
