The Vikings earned their first win of the season with a 34-10 beating of the Cardinals on Sunday afternoon. After a few weeks of struggling in the second half, Adrian Peterson powered in for three first-quarter touchdowns to build a cushion so big even Minnesota couldn't lose it. "It felt good just to get a 'W' first and foremost and get out of this slump. It was a good test for us, and we did what we've been preaching," Peterson said.
