I have been a long time lurker and I really have enjoyed reading the forum in the last few years. I have a lot of respect for the basketball knowledge and insight that many of you guys possess. I saw this topic and thought it might be a good place to insert my first thought. With that being said...I hope everyone will be easy on me on my maiden voyage. Lastly...I want to apologize up front for the length of this comment. It will not be typical of my comments in the future.
The biggest issue with the NET is....the advanced metrics are weighted far too heavily. IMO....predictive analytics don't really work in college basketball. There are too many teams (364) and there is no way to accurately quantify home court advantage. Home court advantage and the matchup are the two most influential variables in determining an outcome in college basketball (when comparable talent is displayed), yet neither are accurately portrayed in predictive analytics. How can you use an model when the two most important variables are not part of it? The tournament committee keeps tweaking the criteria by adding more analytics that are basically spitting out the same data...that seems redundant. Home court advantage and the matchup both play direct roles in determining the outcome of a game, whereas offensive and defensive efficiency metrics have been formed by those factors, making them a byproduct of the true determining factors in the outcome. The committee insists that the NET is just used as a sorting tool, which hopefully is a fact. Because....any evaluation tool that de-emphasizes or minimizes the outcome is flawed by nature.
Every year there are 1-2 teams that are negatively affected by conflicting analytics/results profiles. This year...Creighton is that team. The Bluejays NET ranking is 35 with the following resume-
16-6 Overall (9-2 T-2nd Big East)
SOS: 33
Result-Based Metrics
KPI: 32
SOR: 21
WAB: 29
Predictive Metrics
BPI: 26
POM: 32
T-Rank: 32
Quadrant Records
Q1: 4-4
Q2: 5-2
Q3: 2-0
Q4: 5-0
For comparison....here are a couple of resumés of higher ranked teams-
Texas
NET: 25
15-7 Overall (4-5 T-10th SEC)
SOS: 23
Result-Based Metrics
KPI: 52
SOR: 39
WAB: 35

BPI: 21
POM: 29
T-Rank: 27
Quadrant Records
Q1: 4-6
Q2: 2-1
Q3: 1-0
Q4: 8-0
Michigan
NET: 16
16-5 Overall (8-2 3rd Big Ten)
SOS: 46
Result-Based Metrics
KPI: 8
SOR: 22
WAB: 26
Predictive Metrics

Q3: 7-0
Q4: 1-0
As you can see....the supporting numbers don't match up with the resulting number. So...it's a good indication of how the efficiency stats affect the ranking. Obviously, the Texas resume isn't as good as Creighton, yet ranked 10 spots better. That means...if the tournament committee used the NET for seeding, Texas would be 3 seed lines ahead of Creighton. The Michigan resume is very similar. Even if you think Michigan's is slightly better...it's certainly not 19 spots (5 seed lines) better. And, those are only two examples. Creighton's resume is as good or better than just about every team ranked between 16-34 in the NET. I think Ken Pom or Bart Tovik both do a good job with what they do. I just don't think the data they are working with is based on the most valid information, therefore it shouldn't be a heavily weighted data point in determining team rankings. I mean, any metric that still has Houston ahead of Auburn is not a data point that should be highly regarded. Ultimately, it only matters how the tournament committee accesses it. I guess we'll see what's important in March. There's plenty of rhetoric bantered about every year regarding selection and seeding, and...this year won't be any different.
Thanks again. Look forward to talking with you guys about Creighton basketball going forward.
