Duke, Michigan, Arizona, Florida have separated themselves

Four teams — Duke, Michigan, Arizona, and Florida — have separated themselves as the clear top tier in college basketball as conference tournament week begins. Jon Rothstein breaks down why those four programs stand above the rest and what it means for the race for No. 1 seeds in the NCAA Tournament. Plus, hear from Michigan head coach Dusty May on where his team stands entering the postseason. We also take a deep dive into the conference tournament brackets across the ACC, Big 12, Big East, Big Ten, and SEC, react to the final AP Top 25 of the season, and run through the latest news and notes from around the country — including Nebraska tying a school-record 26 wins under Fred Hoiberg, St. John’s winning the Big East regular season title outright for the second straight year under Rick Pitino, and Donovan Dent’s incredible assist-to-turnover stretch for UCLA. Finally, we highlight several potential bid stealers to watch as championship week unfolds.
