I watched a few touchdowns followed by PATs, TV timeouts and touchbacks over the weekend on NFL Game Rewind, and this is an estimate of how much time there is several times per game when absolutely nothing happens:
PAT—About 55 seconds from the time a touchdown is scored until the time the ref signals for a TV timeout.
TV timeout—There are 20 per game, at 1 minute 50 seconds per timeout.
Touchback following the TV timeout—About 75 seconds from the time the game comes back from commercial to when the offensive team breaks the huddle and approaches the line for first down.
That’s exactly four minutes between plays of substance—the touchdown and the first play on the next series—assuming a PAT and a touchback. That’s a lot of nothing time. There were only 59 two-point conversions attempted last season, about 3.5 per NFL weekend. Those are fun plays, and the NFL should put a rule in place to encourage more of them. Pushing the PAT back is the first step in that direction. It may not be enough, but it’s better than the 19-yard gimme that exists now.
