Answer:
Well, the old play clock(the 25 second one used last year but start when officials marked the ball for play) gave it average about 20 seconds rest depending on how fast you wanted the ball snapped. Now this year, it will be a 40 second play clock, improving the rest time from a 22 second rest period to a 28-30 second rest period. This is just an estimated guess on the averages, give or take.
