Passage: Still searching for their first win of the year, the Chiefs went home to play a Week 3 interconference duel with the Minnesota Vikings.  Very much a tale of two halves, Minnesota dominated through most of the first half.  Larry Johnson of the Chiefs was ineffective against the Minnesota defense while Adrian Peterson rushed for 102&#160;yards and a touchdown (mostly in the first half).  After making changes during halftime, the Chiefs returned with a passing game and an amped up defense.  The Chiefs' Jared Allen, back from suspension, led the defense with eight tackles, two sacks, and a forced fumble, shutting down the Vikings' offense.  Chiefs' rookie Dwayne Bowe, with one reception coming into the game, benefited from the second half passing game with five receptions, including a touchdown.
What was the Chiefs second half game plan? Who was winning at halftime?
