It’s the first installment of 4-on-4 here at WNUR, where four of our broadcasters answer four questions about happenings in the world of college (and often Northwestern) sports. As yesterday was selection Sunday, Michael Stern (@michaeljstern23), Ari Ross (@aross50), Ryan Fish (@ryanmfish), and Josh Burton (@josh_burton1) reveal their final four teams, sleeper picks, and national champions. The quartet also predicts the fate of all seven Big Ten teams in the tournament.
