A season of electric slides, potato-sack relays and "duck, duck, goose" proved one overriding point for the NFL: Big problems really can be solved.
I'm only half-joking. Maybe you enjoyed some of the elaborately planned celebrations that players have performed after scoring touchdowns or making big plays this season. Perhaps it wasn't your thing. But if nothing else, the NFL successfully walled off a self-inflicted source of damaging criticism by relaxing its unsportsmanlike conduct rules to reflect the reality of modern entertainment.
The annual "No Fun League" narrative largely vanished and was instead replaced -- appropriately -- by smiles, fun debates and the occasional internet dash to Google the references.
