  How did the referees miss the grabbing foul?

It appears each of the 3 refs are looking at the right spot. The two that remain in the frame of the live shot appear to have a clear view.  (The baseline ref can be seen to have a clear view in the replay.)  I often wonder how refs call fouls when players' bodies block their view. X-ray vision?   But that wasn't necessary here.

3.5 minutes to end of game with a 9-point differential.  Maybe the refs were ruminating on their whistle.
Oh wow, at this point in the game, Texas had 1 player fouled out and 3 with 4 fouls.  Baylor had one player no player with 4 fouls (one got 2 fouls called after this, giving her 4 for the game).
Well, Texas is coached by Vic Shaeffer.

Oh, by the way, the AP reports "For the first time in the 47-year history of the Associated Press women's basketball poll, no team from Texas is in the Top 25."   Adds insult to injury.
