Mapping out Favre's playing time

Posted by ESPN.com's Kevin Seifert
Brett Favre likely will play the first half of Minnesota's next preseason game, a nationally-televised (by ESPN!) matchup Aug. 31 at Houston. That's about all we know for sure about Minnesota's four-man quarterback situation.

Coach Brad Childress confirmed his plans for Favre this week during a news conference Monday but said he hadn't decided if Favre would play in the Sept. 4 preseason finale against Dallas. Childress also said it was possible he will keep all four of his quarterbacks on the final 53-man roster this season, but I tend to doubt that as a realistic scenario.

Childress has been all over the map for his strategy in the final preseason game. In 2006, he played his starters for almost a half. During the past two seasons, however, most starters did not see the field. Following that recent trend would leave Favre with less than three quarters of preseason playing time entering the regular season. But starting him against the Cowboys would also mean using the Vikings' No. 1 offensive line, an additional burden that must be considered.

As for his final depth chart, the Vikings ostensibly are conducting a competition between Tarvaris Jackson and Sage Rosenfels for the No. 2 role. There's also no guarantee that John David Booty will be the No. 3 quarterback; Booty has practice squad eligibility.

Childress: "Those conversations would definitely be internal. I don't think they're external at this time, but [the media] are free to conjecture and make your fantasy roster for the Vikings."

Well, since you asked: Conventional wisdom has suggested that Jackson will find himself on another team's roster when the season begins. While I'm not convinced Childress is ready to part ways with Jackson, I also wonder if he would sacrifice depth at another position to keep all four quarterbacks on his active roster.
