ROSEMONT, Ill. — With 1:21 left in the first half of Wednesday night’s game against Minnesota, freshman Anthony Gaines grabbed a missed shot and raced up the court with a full head of steam. Ignoring the pleas of his coach, he dribbled past Scottie Lindsey and Bryant McIntosh, Northwestern’s two primary ball-handlers. A Minnesota defender put his body between Gaines and the basket, but a swift behind-the-back dribble gave the freshman a clear lane to the basket. Gaines took the ball up strong and drew a foul, nailing two free throws moments later to push the Northwestern advantage to 41-17.
