Suddenly, Brett Favre looks more like a surgeon than a gunslinger.

Seven games into his tenure with the Minnesota Vikings, Favre has thrown only three interceptions and is completing 68.9 percent of his passes - more than seven points above his career average.

So far, the NFL's career interceptions leader is playing within the structure of the Vikings' offense and taking advantage of the talented players around him. But Sunday's mega-matchup with the Green Bay Packers at Lambeau Field will be a significant test to Favre's newfound discipline.

Favre will have to handle an improving Packers defense, a potentially ornery crowd - and his own emotions returning to the place he played for 16 NFL seasons. Favre says there's no secret to handling emotion in big games, while Packers players insist anyone can be forced into mistakes under pressure.
