One of the National Invitation Tournament semifinals set for tonight is a rematch. The other is a preview – of a pending conference rivalry. Maryland faces future Big Ten foe Iowa in the second semifinal tonight, after what should be an entertaining, up-tempo matchup between Baylor and BYU, two of the nation’s better offenses. The Cougars visited the Bears three months ago, and it didn’t go well for them as Baylor won 79-64. But this time the teams will meet on neutral hardwood at Madison Square Garden in the 76th NIT. The doubleheader begins at 4 p.m. on ESPN2.
