It's crunch time for bubble teams. There are always winners and losers. It's always contentious. A couple of years back, they added 4 more teams to the mix. So 4 more teams are happy. But that didn't change the angst among the rest one whit.

Is 68 teams the best answer? What do you think?

Stat Dive (part 27): Conclusion, Resources

Conclusion​

One of my "Someday" projects has been to gather basketball data and test Dean Smith's possession theory against those of Dean Oliver, Ken Pomeroy, and the like. I also wanted to see how the game has changed. Getting the data for this project was always too expensive of a proposition. Over the past few years I've downloaded certain NCAA.org tables at tournament time, but the idea of downloading 16 tables for each of the 23 years, lining all of the teams up on a spreadsheet, and cleaning up the columns seemed like a daunting task.

In late January I discovered a deep link to those NCAA tables, and using software that I wrote, I was able to get the data into CSV files for each year, then import them into Excel pretty easily. Updating this year's stats each morning now takes all of 8 seconds for me, and you can download these daily updates using the link in the resources below.

I learned much in this journey. I've been focusing on too many variables and on the wrong variables. Knowing that the modern theory of points per possession and Dean's theory are, in the end, equivalent, now has me pondering a conversion of all of my data so that it can be equated with today's public conversations. (Though I still maintain that Dean's method is a more pure assessment of each offense and defense).

Does all of this make the NCAA Tournament make more sense? Probably not. A large one-and-done tournament is a pretty silly way to determine what the best team is. It's till The Most Wonderful Time of the Year, though.

I will be back to amend this series from time to time, I'm sure. I've just figured out how to download all of the box score data since 2012, so that might generate some notable observations.

Thank you for sticking through this. I originally thought this would take about 10 installments, but I kept discovering more interesting correlations, trends, and exceptions.

of course ESPN would not make the Carolina win over Duke the lead story.

South Carolina’s miracle win was number one then Boston beating Phoenix in a NBA highlight then the Carolina win which lasted maybe 30 seconds. Absolutely no mention of Flip lifting his leg to trip Ingram which the entire nation saw nor the Duke fans after the game throwing objects at the Carolina players. Did anyone else notice how quickly ESPN changed programming after the final buzzer. No post game at all just like two years ago. Also after watching the replay as I felt at the time the clock operator did not start the clock for three seconds late in the game after Duke inbounds.

NET Rankings Tracker

Initial rankings came out several days ago and I believe UNC came out of the gates at #32. After the loss to UConn, we dropped to #37.

A bet I would place all my money on no one guessing correctly, is the current #1 ranked team. None other than the mighty cougars of Brigham Young University. Yes, you read that correctly. I only post this part to see some of you blow a fuse over the science of the NET rankings.

Now I’ll slowly step away to watch the comedy take place. Have a great night. 😁
