Starters listed first. BLK is the NCAA total: a solo counts 1, a block assist ½. Recaps and press releases usually quote solos + assists instead, so the same night can be reported as a bigger, whole number. The box score is the source for every counting stat on this page.

Slot = rotations since the start of the set (slot 1 is the lineup a team opened the set in), not a fixed player alignment. Only clean sets count (3 of 3 here): sets where the NCAA play-by-play has gaps or score corrections are left out because the rotation can't be tracked through them.
