Small thing and I have mentioned this before- run the clock after the TD on into the try as a regular scrimmage play. While I've performed no formal study, I would estimate it takes a minumum of 45 seconds to a minute to get the XP team on the field, lined up, and the kick completed- then we go into a 1 min. intermission prior to the subsequent kickoff.
A low scoring game, no biggie, but how many of those are there now. In your usual 56-14 blowout, that is about 10 minutes.
