EDEN PRAIRIE, Minn. -

Minnesota's offense has a simple focus: Adrian Peterson. The Vikings aren't scheming to surprise opponents by throwing 50 passes per game.

That doesn't mean offensive coordinator Bill Musgrave doesn't have plenty to work on. Just because the Vikings have a straight-forward, no-frills style doesn't mean Musgrave hasn't had to dig deep in the playbook to find combinations, alignments and calls that work to keep the attack balanced and the defense guessing at least some of the time.

Coaches and players have credited Musgrave for his ingenuity, particularly over the last month as the Vikings won four straight games to force a rematch this Saturday with Green Bay in the playoffs. In Sunday's win over the Packers, Musgrave unveiled several wrinkles that allowed the Vikings to accumulate a season-high 444 yards.
