IT IS almost pointless to ask ourselves whether the NFL has figured out Chip Kelly, because figuring out things is what the NFL does. The players say that the letters on the shield offer an accurate appraisal of their job prospects - Not For Long - but reallly they sum up the entirety of the league.
Every team employs legions of minds whose sole job is to figure stuff out, and those minds do not sleep until they succeed, or until they are fired. The NFL is a fascinating study in survival of the fittest, one team's adaptations prompting another team's counteradaptations to create a sport whose equillibrium is hyperevolution.
