Conference tournament week has arrived, and with it a chance for historic selections (and snubs) for this year’s NCAA tournament field.

By beating North Carolina, Duke raised its profile enough to be back in the at-large discussion.

It might seem early for bid thievery, but it has already arrived with a major shuffle on the bubble.

The rankings might — might — offer a clue on what this committee might or might not value as much.

For the second time in three weeks, Northwestern toppled the undefeated No. 1 team in the nation, which now poses the most important question: Who should be the No. 1 seed?

With its loss to Michigan on Saturday, Penn State now owns three losses outside the top 20.

It’s not too late for Duke to begin building a case to reach the NCAA tournament. Still, the Blue Devils can’t wait too much longer to do so.

The seedings are the same as a week ago — but the bubble has grown.
