The Bears are who we thought they were, are the Vikings?

This is a big week for the Minnesota Vikings. Yes they play the Detroit Lions. Historically the Vikings have always played down the level of their opponents. They've always been competitive and played well against the better teams. So this is a big game in my eyes.
We've been told time and time again about their offensive weapons and crushing defense. Well they won't find an easier opponent than the Lions. They have to come out and win convincingly. This is what Brett Favre is for more than anything else. To provide a veteran leader who doesn't overlook an opponent. It was just last year that the Vikings were lucky to win both games against the Lions. The Vikings are supposed to be better this year. Great teams don't struggle with teams like the lions. I am certain that the Vikings won't go undefeated, but this can not be one of their losses. There isn't anything good that can come from a loss to the Lions. The Vikings can't lose this game, and then beat the 49ers and Packers, and say they wanted to be 3-1 after 4 games. The Saints just threw 6 touchdowns against the Lions, so Favre should be licking his chops.
Here is what I need to see. The Vikings need to score on their 1st possession. Favre and AP need to run and throw for a combined 400 yards. The defense needs to hold the Lions to under 14 Points. The special teams needs to play well. And I never thought I'd hope for this, but I want to see T-Jack playing in the fourth quarter.
