Here's a look at where the ACC's men's basketball programs rank, with Duke on top and Louisville moving up to No. 2

Johni Broome 's injury makes Auburn's spot more tenuous, but the Tigers beat Mississippi State by 22 even without him. Duke is barely breaking a sweat while blowing out inferior ACC competition. And then there's Iowa State, which has only a two-point loss to Auburn blemishing its résumé and just dispatched Kansas by 17.

Once again this week, it’s a three-way tie for the lead atop the Big 12 Conference basketball standings. And while the top three in this week’s power rankings remain the same from the week before, there was quite a bit of movement from fourth on down to the very bottom.
