NCAA Tournament began with 68 teams earlier this week, and the bracket has now been reduced to the Sweet 16. With regional semifinal matchups set with the conclusion of the second round, scouting work has already begun for the teams just two wins away from reaching the Final Four in San Antonio.

Danny Wolf, Michigan: Wolf is the definition of a unicorn with impressive skill at 7-foot. He played some of his best basketball in Big Ten tournament wins over Maryland and Purdue. A storyline to know: Wolf, a Yale transfer, could play his old team in the second round.

For the first time since 2008, the Final Four will consist entirely of No. 1 seeds, with No. 1 overall seed Auburn becoming the last to join Florida, Duke and Houston in San Antonio after a 70-64 win over Michigan State in Atlanta.
