The on-air duration of an NFL game is actually closest to 3 hours. It's 2 to 2.5 hours when shown without ads.
The NFL GamePass service that you can subscribe to (how I mostly watch the NFL from outside the US) offers 'Game in 40 minutes' (sometimes called Condensed). It just cuts from play-to-play-to-play. It's a great way to be able to watch a couple of other NFL games in a given week (fits nicely into a lunch break), but I do actually miss the proper commentary. Good commentary teams are very helpful in breaking down what happened in the blur of action that is each play.
