Conventional wisdom says the Vikings can be put in a box and defeated because they cannot think outside it, a notion that has defined this season's failures.

Opponents work a comfortable lead, crowd the line of scrimmage with defenders, force running back Adrian Peterson to power through the mismatch, dare quarterback Christian Ponder to beat them downfield with a passive passing game and then grind Minnesota's defense to a nub.
