accelerated clock does make the game more real! When you line up to the line with accel clock on you have around 19 secs to hike the ball which is more like real life instead of picking a play right away and having 38 secs to hike the ball. You also get to play with higher quarter lengths with it on instead of trying to figure out how long you want your quarters to be to get the right amount of total plays for each team. DUR!!!
