The Church (capital C) is my number one passion after God & family and the NFL is my number one hobby. Throughout my history with each of them I've noticed some common things between the two of them, but in some cases it SHOULD be common but it usually isn't. I'll post them all in no particular order.
Excellence
The NFL bleeds excellence. The casual observer may not notice, but from the TV production all the way to the details in practice, excellence is prevalent. The parity in the NFL is so great that the worst team one year can make the playoffs the next year. One reason for that is because the level of excellence across most of the teams is very close which leaves little room for error. It's the reason a winless team could beat an undefeated team 5 weeks into the season.
Churches are rarely seen as excellent. Plus, excellence is a word/label that can be abused or sought after at the expense of more important things (like people). For the purpose of this post, I'll borrow a definition of excellence that says it is "doing the best you can with what you have, in a sustainable fashion." (Thanks Troy Fountain via Rich Barrett). Churches definitely have a great disadvantage when talking about excellence in comparison to the NFL, or any business, because the vast majority of their "staff" is volunteers. But, they should do the best they can with what they have, and not settle for mediocre.
A big reason why the NFL is so excellent is because of focus. All throughout the NFL they apply great focus which allows them to pour the necessary resources and time into the most important things. Churches typically dilute focus by doing too much. NFL teams take this to an extreme, constantly preaching one game at a time. John Harbaugh brought an acronym to the Ravens that drives what they do every week, and it's What's Important Now?
If the churches would choose to focus on a handful of things, and trim out everything else, we would see a dramatic difference in the level of excellence in the things they continue doing. Unfortunately the pain from a lack of excellence doesn't feel worse than the perceived pain of cutting programs or events.
