[Actually, Nneka's first two 3pt attempts of this game were as the shot clock ran down. The first was an air ball 30 seconds into the game. The other 3 attempts were successful. Chiney's comments about encouraging Nneka to shoot 3s at the end of the clock were interesting.]
As was said, rating systems generally have problems, partly because of the sparsity of data. There are too many variables and too few constraints. Consider North Carolina. By RPI, it is 89th; by Sagarin/CBN it is 41, a dramatic difference. It has 3 wins above RPI #84: Miami(#24), 2x Wake Forest (#49). It has a loss against RPI #246. All the other wins are against teams #84 or lower; all the other losses are against teams #32 and higher. So, you've got about 50 places (#32 to #84) that you could put it in.
Look at Stanford. A loss against RPI #3; Wins against #5, #21, 3x #30, #38, and the rest are #55 and lower. You'd have a strong case to put it in the top 30, but not as clear that it should be in the top 5.
Look at K.al. 3x losses against #2, loss against #13, 2x losses against #38. Wins against #49, #51, and lower. Why should it be #30 ??
The NCAA RPI system has gotten its little tweaks, like epicycles in the Ptolemaic system, but still isn't great.
(Note that the incestuousness of play within conferences contributes to the too little data, and tends to keep conference teams bunched in RPI, not to mention share a lot of their OWP and OOWP)
So now you look at things like home/neutral/away wins/losses. Still not enough data. Then you look at score differential. But that has the problem that most coaches try to avoid big differentials, and also avoid too much playing time by their best players. But not all coaches.
Scoring differential and top 5 player average playing time
- UConn (+30.6pts): Hartley: 32.8 min, Hayes: 30.4, Faris: 28.7, Mosqueda-lewis: 27.9, Dolson: 22.8
- Stanford (+22.2): Nneka 29.8, Toni 29.6, Chiney 28.7, La Rocque 23.5 Tinkle 22.7
- ND (+27.5): Diggins 30.2, Mallory 28.9, McBride 27.3, Novosel 26.1, Peters 24.2
- Baylor (+27.3):Â Griner 32.3, Sims 31.9, Hayden 25.9, Williams 25.3, Madden 24.6
Is the lesser time for Stanford due to easier opponents, injuries, or what? Does the difference in scoring differential reflect dominance or just the coach's preference.
Should one pay attention to the point differential when the quality of the teams is vastly different. Do the big wins by Stanford against ODU and UC Davis matter at all? (So the question isn't whether you win by 100 or not. It might be whether you win by 10 vs by 25. Or, better, how far ahead were you when you were playing with mostly reserves, and how early that was.)
Would a more complicated computerized rating system work better? No doubt. Would it be correct? No way.  I haven't mentioned the effects of injury, suspensions, illness, etc. and their effect on games past and future. We've seen teams that share an illness among themselves and play poorly for a game or two. We've unfortunately seen injuries that, even if you discount the injured player, disrupt the performance of the team as they adjust to new responsibilities. What about the issue of young teams? No doubt K.al has improved over the year relative to most other teams because the younger players (and coaches!) gain experience more quickly. (I feel confident they would beat Rutgers now.) How do you put this into a rating system?
Then there's head-to-head styles of play, and players themselves. I'm afraid that at this point, I don't know how well either K.al or Stanford would do against Baylor. To compete against a dominant tall player, you need more 3pt production than either team has shown. (I know Stanford has the potential for such production.) [I think our best chance against Baylor is to try to use the quickness of the O-team to draw fouls by Griner. One block her out and the other go to the boards. But Griner is probably too smart for this, but it could affect her play.]
So, the NCAA gives wide latitude to the judgement of the committee. That means that personal preference, rather than objective measures, are used for the ranking. We tend to notice the East Coast bias. (By RPI, U$C should easily be in the tourney. By Sagarin/CBN, they are on the bubble. By East Coast Bias, who are those guys anyway? Hey, about UNC, that went no further west than Atlanta, and played 3 of the bottom 50.)
