The tension between Vikings coach Brad Childress and quarterback Brett Favre is because of the latter's propensity to audible. Childress has a reputation for limiting his quarterback's audibles and Favre believes that his experience and knowledge should give him the freedom to changes things when he sees fit. "He and I talked, as we have all year," Favre said, adding that given the team's recent slump, "the frustration is gonna show." "It's gotten blown way out of proportion," he said.
