When Yale took their big off the floor and moved Townsend to the 5 I felt we actually did better defensively with Lyles on Townsend. Yale still scored, but at least the shots they were taking were more challenging. We made it too easy for them in the 1st half.
In hindsight we probably should have mixed up the defense more frequently. Throw zone a few possessions, play some man, and sprinkle in some hard double teams here or there. Running the same defensive set for long stretches made it too easy for Townsend to disect the defense.
