As regular college basketball watchers know, the ability to win on the road is one factor that separates the good teams from the potentially great ones. As a result, our latest bracketology has a change on the top line as Arizona replaces Tennessee as a projected No. 1 seed.

The Wildcats had to work overtime to win at Utah before facing a quick turnaround against a Colorado squad that desperately needed a quality win. But the ‘Cats were all business, completing the weekend road sweep in blowout fashion against the Buffaloes. On the same day, a red-hot Tennessee team got cooled considerably at Texas A&M, making the Volunteers’ stay as a No. 1 very short lived.

The other three regional headers remain the same as, with Connecticut, Purdue and Houston all posting wins over the weekend.

In other moves, Clemson and Virginia are trending in the right direction, Wisconsin and Kentucky are headed the opposite way, and a six-bid Mountain West Conference remains a possibility.

Last four in

Mississippi, Utah, Nebraska, Nevada.

Next four out
