If the third preseason game is the dress rehearsal, then Week 4 often provides the blooper reel.
Generally speaking, most teams want to play their starters as little as possible in Week 4 and make sure everyone is healthy for the regular season. This leads to extended time for not only the backups, but also for the deep reserves, and it results in some of the least watchable football of the entire league year.
In the most positive terms, some teams will use this final exhibition game to help sort out the final couple spots of their roster, but for the most part, these are games that most players, coaches and executives would rather be able to hit that same "simulate" button most people do when this game comes up on Madden.
Still, some teams still have work to be done and some players still have cases to make—rookies who haven't quite stepped up as expected or veterans thrust into position battles they didn't expect. Maybe it isn't just a defined roster spot or role they're fighting for; it's also a matter of making a case to the rest of their teammates that they can be trusted.
These guys have one more week to state their case to the entire league.
