In the process of getting stomped by Texas Tech 85-49 Sunday night, Northwestern brought out a trick from the earlier Chris Collins days — the zone defense. After the Wildcats fell behind 20-5 early, Collins pivoted to a zone for the rest of the first half. Northwestern opted for the zone on two different occasions in the second half. My back-of-the-napkin math says that Northwestern played zone on 30 possessions and man-to-man on 29 possessions (I excluded everything inside of the six-minute mark when the starters for both teams came out).
