The clock is ticking as we continue the countdown to Selection Sunday. This is, without a doubt, the most intense week of the season. Some things are already in place, but so much is unknown. As the NCAA men’s basketball committee gathered in Indianapolis Wednesday to go through its final steps, chair Scott Barnes said selections on the top two lines are uniquely clear. But there is a lot of work to be done on seeds from No. 3 to No. 9. Kentucky will be the overall No. 1 seed as the Wildcats continue their pursuit of perfection. Bubble teams are trying to impress. Defending national champion UConn needs four wins in four days just to make the field. Yale and Harvard will hold a playoff to determine the Ivy League’s automatic bid. The waiting game is painful at schools such as Murray State and Iona. And Cinderella is out there somewhere. Here are the final power rankings before Selection Sunday. – Ken Davis
