... about a sport like the NFL is just how ephemeral our conclusions can be.

For instance, this was written in total seriousness less than a month ago:

"There's plenty of head-scratching going on over the sudden collapse of the Broncos, but when the team is 25th in points per game, 19th in passing offense, and just 16th in rushing offense, not to mention allowing 117 points in four games against the Redskins, Chargers, Ravens, and Steelers, it's safe to say things aren't turning around anytime soon.

The Broncos don't have an impossible run down the stretch, but with games against the Giants, at the Colts, and at Philadelphia left to play, don't expect any Lazarus jokes this season."
