The Iowa Hawkeyes crushing defeat ended the season before anyone really expected it to.
It wasn’t because of the defense. Outside of the anomaly of all anomalies (at Rutgers), every time Iowa held an opponent under 70 points, it resulted in Hawkeye victory. 67 points is a winning number for an Iowa basketball defense. No defense is going to be perfect - the Hawkeyes certainly weren’t today with Richmond hitting on their signature backdoor cuts - but they did enough on that end of the floor.
The defense, on a per-possession basis, was better than 10 of the 14 prior games.
