Interestingly, he did go the 'other way' for long stretches when Stokes was on the floor - Kiah (1) was in tight around the rim essentially playing that zone while the other (4) played in a match-up zone that looked more like a man-to-man, since UCONN defenders were playing people tight and following them around. Hard to describe that part of the defense as 4-on-5 because Stokes always had a bead on somebody in the lane. Sort of the anti- box-and-1. Not a classic zone by any stretch, though Geno did use that defense at times as well.
I'm not saying this was the defense whenever Stokes was in the game, but it was employed quite a bit (only with Stokes)
