The 40 second clock is only running after a pat and after a kickoff. The teams still have 2 min between pat and kick off, tho most come out after a min of so. After a kickoff, the crew will take some time to set chains, make sure all officials are in position, if the 40 second clock is close to expiring it will be pumped back up to 25 if the delay is on crew or some problem with the field, or say an injury on the kickoff.
