Post Entry Pass and Big Man Touch Study — Duke vs Presbyterian
You might notice a slight change in the title of this post from the previous one regarding this study. Based on feedback I received from the charting of Duke’s first game against Belmont, many readers wanted to see not just who was making and receiving post entry passes, but also how many times Duke’s bigs received the ball within the flow of the offense.
Statistically, there is really only one measure that can be calculated that can even come close to figuring out how much a player is used on the offensive end. However, that stat (usage % is somewhat limited.) Let’s look at the formula and I’ll explain why it is limited and why the only way to truly calculate how many times a player is “used” on a team is to go back and review the tape.
Usage % (or Rate) Formula: 100 * ((FGA + 0.44 * FTA +TOV) * (Tm MP / 5)) / (MP * (Tm FGA + 0.44 * Tm FTA + Tm TOV))
If that doesn’t make sense to you, don’t worry. I’m not going to delve to far into the mathematics of it, for simplicity’s sake. What is important is the concepts behind the numbers. According to college basketball stats guru, Ken Pomeroy, he calls Usage Rate “Percentage of Possessions Used.” His description makes sense and brings those numbers into plain English:
Percentage of possessions used (%Poss): A measure of personal possessions used while the player is on the court. Simply assigns credit or blame to a player when his actions end a possession, either by missing a shot that isn’t rebounded by the offense or committing a turnover.
This formula, while the best there is available to people just looking at the box scores, heavily weighs aggressive players who take a lot of shots, commit a lot of turnovers, or make a lot of assists. Since Duke’s possessions often results from multiple passes, players do not get credit for their role within the offense when their actions don’t contribute to the end of that possession.
A big reason why I undertook this project was to see just how much of an impact duke’s big men were having in the offense. As the best available formulas out there are limited, the only way I could truly do this is to look at the tape. The added “Big Man Touch” stat (now known as BMT), will help to do this. Unfortunately, it’s nearly doubled the time it takes for me to record the stats. Bear with me as I wade through the mountains of data.
Let’s look back on the methodology for post-entry passes that I laid out in the Belmont post. Read more
