BOOSTING THAT OFFENSIVE EFFICIENCY RATING. I last had to think about that in high school. In basketball, it's the ratio of points to possessions, and one way to boost it is to commit fewer turnovers. The Wisconsin Badgers limited their turnovers to one, in the first half of their win over Michigan State. The opponent's offensive efficiency rating is the team's defensive efficiency rating (there's a relative-prices flavor to that) and the aforementioned Badgers limited sharpshooter Drew Neitzel to all of one trilighter, which had only a slight effect on State's points per possession.
