Update: Four factors for every game
If you don’t know, the four factors explain why a team wins or loses. They’re the building blocks to efficiency. The four factors are:
- Shooting (eFG)
- Avoiding turnovers (TO%)
- Offensive rebounding (OR%)
- Getting to the foul line (FTRate)
I’ve now added four factors and points-per-possession (PPP) for every game since 2003-04 on this page on the site.
This was a tall task. For any games from the ‘03-04 to the ‘06-07 season, the four factors had to be calculated manually. I even built a four factor calculator to make this a bit easier.
At the start of the ‘07-08 season, a great (and free) site came in handy: barttorvik.com
While most people are aware of kenpom.com, Bart Torvik’s site is on the same level. Tons of useful information, including box scores since the ‘07-08 season that calculate some of the four factors for you.
Here are a few interesting tidbits using this four factor information:
- The 2009 Championship team scored over 1 PPP in every single game
- The 2018 team scored the lowest PPP in a game (0.62 against Michigan State) and also scored the highest PPP in a loss, 1.28 against Miami’s 1.32 PPP
- The 2004 squad attempted 50 free throws and 51 field goals in a win against Maryland, good for a 98.0 free throw rate
Hope to do more with this data in the future.
Mobile access
It’s been a challenge to present all this information in a way that’s useful on mobile devices. I’ve made some adjustments to make the tables and information easier to access.
For example, here’s how the officials page looks now on mobile:
The same changes exist for all other tables on the site. Big thanks to Matt Smith, and his recommendation on a simple responsive table.
