Andrew Luck dinked and dunked passes, winged a few into impossibly tight spots. Stepfan Taylor churned out yards, more than he ever had. The big, powerful line seemed to get better and more bruising as the game wore on. Balanced and efficient, Stanford was a lot like Arizona would like to be -- heck, any team would like to be at this point. Luck threw for 325 yards and had both of his touchdown passes in the second half, Taylor ran for a career-high 153 yards and the sixth-ranked Cardinal pulled away for a 37-10 victory over Arizona on Saturday night in the Pac-12 opener for both teams.
