Let me start by acknowledging that refereeing is difficult. Most of the time, they don't get the benefit of replay. They are often blocked from seeing a foul (and, IMO, guess). The audience has a different view, which leads to different perceptions of what is or isn't a foul. They have to make a quick whistle or someone will question a "late whistle".
As I understand it, in half-court play, each official has a position they take and each has a responsibility for what they view. It seems they rotate among the positions, but I haven't understood how that is done. I have a hypothesis that each official should see approximately the same number of fouls (judged by some all-seeing, all-knowing oracle) in a game, and that the ratios of those fouls on each team should be approximately the same, and mostly independent of previous fouls.
Given that, as I watched this game live (on TV), I felt one official was calling a large number of fouls on one team, and most of his calls were against that one team. So I investigated.
The box score statistics don't show which officials call which fouls. So I watched the video to see which official called which fouls on which teams. (In some cases there are two officials seemingly both calling a foul, so there are more credits to officials than fouls.)
The stats I did on the calls in this game look even less likely statistically than even I thought.
Here are the calls by the 3 officials. "C" means the call was a foul on Colorado.
Ref1: SSSCSSCSSSSSSCC S:11 C:4 (S: 73% 61% of the calls made against Stanford. 45% of all the foul calls.)
Ref2: SSSSCCSSCS S:7 C:3 (S: 70%)
Ref3: CCCCCCCS C:7 S:1 (S: 12.5%. 50% of the calls made against Colorado.)
NOTE: Ref1 made an emphatic call against Stanford on the first foul. It was overturned, apparently by another official (could Ref1 be so emphatic and then, in retrospect, be able to say the defender was in the circle?). I leave the credit as a call against Stanford for him, but I have no other ref that I can credit the correct call. Ref3 started to run down the court. Ref2 didn't make any move on camera toward Ref1.
NOTE: These statistics only cover foul calls made, not counting the intentional fouls at the end of the game. (I don't count them as they aren't judgement calls.) They don't cover any 50-50 calls on out-of-bounds. They don't include any calls that might have been made but no one called it. The only items in the stats are the calls these officials chose to make, not ones they chose not to make. I don't consider the timing or order of the calls, nor the nature (such as resulting in FTs or fouls on key players) of the foul calls.
NOTE: I am NOT saying that any of the refs made calls one way or the other intentionally or even unintentionally. I am not saying that any of these calls might not be fouls, as called (except the overturned one).
I am saying the statistics look strange to me, despite it being a small sample of calls. I suggest it would be interesting to see statistics of these individual refs in other games and in other crews. It would be interesting to see the statistics for referee crews that are disjoint from this one.
I'm no statistician but I think this would be strong evidence that calls are not random with equal probability. I imagine in any experiment, Ref3 would be rejected as an outlier!
Here is my log of the calls (including some comments that aren't part of the statistics above). If I can see two refs and neither raised a hand to indicate the foul, I presumed it was the 3rd ref that made the call. There could be calls in which one ref in camera made the call, while another ref off-camera raised a hand to indicate a foul and I couldn't see that. When two refs indicated a foul, I presumed that both refs were in agreement as to who was to be charged for the foul, although that is never confirmed.
Game times in parenthesis indicate a comment about something other than a foul call.
Q1 7:25 Ref1 calls a charge on Stanford. It isn't clear who corrected/overruled him because the defender had her entire right foot and half her left foot in the circle. Ref3 runs toward the other end after the initial call, so I guess it was Ref2. FTs
Q1 7:08 Ref1 calls a foul on Stanford for reaching in. This is the one where the ball carrier swings her elbows and strikes Dodson in the chest knocking her back a foot. FTs.
Q1 6:12 Ref2 calls a foul on Stanford on a shot FTs
Q1 5:12 Ref1 calls a foul against Stanford when one Colorado player runs over another.

Q3 (0:57) Ref1 - Refs get to make a lot of 50-50 calls that aren't fouls. Ref1 makes a contested out of bounds call in favor of Colorado
Q4 8:36 Ref1 calls a foul against Stanford on a shot. FTs
Q4 8:07 Ref1 calls a foul against Colorado on a def. rebound attempt.
Q4 6:33 Ref3 calls a foul against Colorado on a shot. FTs
Q4 5:53 Ref3 calls a foul against Colorado.
Q4 (3:24) Ref1 is on the baseline and chooses NOT to call a blocking foul on a Colorado player in the circle who collides with Kiana as Kiana is landing from a shot. How many non-calls are there in a game?
Q4 (3:23) Ref1 50-50 call on a ball out of bounds, given to Colorado
Q4 1:51 Ref3 & Ref2 call a foul against Stanford. (Ref3 indicated who was called for the foul.) I think it is clear that Lacie had the position first. The original video & the replay show that. It was Lacie's 5th.
Q4 0:43 Ref1 calls a foul on Colorado in a scramble.
