Brad Childress said he's not losing any sleep over Brett Favre's health.
Don't believe him.
Sometime before 3 p.m. on Sunday, Childress will make the biggest decision of his career, one that will affect NFL history and perhaps how Childress is viewed in his locker room and in the Vikings organization.
As he nears the midpoint in what has been the Vikings' most disappointing season since 2001, the year Denny Green was fired, Childress may even be facing a decision that affects his job status.
At least in public, Childress has couched the decision purely in football terms. He will assess Favre's health and readiness and choose between Favre and backup quarterback Tarvaris Jackson.
That is the way a fantasy football owner would make the decision. The reality Childress faces is far more complex.
Although he has downplayed it, Childress will have to consider history: Favre's record streak of 291 games started, and Favre's past ability to play well despite injuries.
Childress seems more interested in judging Favre by recent history. Favre reported late to camp, committed 14 turnovers in six games, and ranks 30th in the NFL in passer rating. Only a quarterback of Favre's fame and charm could become a sympathetic figure while performing so poorly.
