Get schooled.
Key sequence: After trailing most of the first half — and by as many as 12 points — Columbia came out and outscored UC Davis 27-10 to start the second half. John Baumann supplied 10 of those 27 points, including three dunks in a 90-second span, as the Lions ran out to a 12-point lead.
Drawing conclusions based on one weekend — in Brown’s case, two mid-week games — is not a recommended practice. Still, all eight teams have made their 2006-07 debuts, so think of this week’s Power Rankings as the jumping-off point for the season.
Key sequence: The Lions stayed with the 12-ranked Blue Devils early on, and trailed 20-14 over nine minutes into the contest. However, a Ben Nwachukwu tip-in gave Columbia its only points during a six-minute stretch, during which Duke went on a 12-2 run to open up a 16-point advantage.
Key sequence: In the first 12:40 of the game, Penn ran out to a 36-12 lead. The Quakers shot 13 for 19 from the field (68.4 percent) and 5 for 7 (71.4 percent) from three-point range in that span. It wouldn’t quite be accurate to say Penn never looked back from there, but the Quakers’ lead never dropped below 10 points.
Key sequence: Yale wrapped a 17-3 run around halftime, blowing open a game that had been respectably close prior to that point. Ahead 28-18 with a little over a minute left in the first half, the Bulldogs scored on nine of their next 12 possessions to claim a 45-21 advantage early in the second half.
