Attempt to find "stat stuffers" 

Post#1 » by Jasen777 » Wed Aug 27, 2014 6:15 am

In wake of a recent thread in general discussion, I wondered if there was a statistical way to find stat stuffing players. For a first run I just plotted points vs. win shares (for the top 103 players in points). Points is the biggest stat stuffing complaint and the idea is to find the players whose points don't lead to wins (or at least win shares), 2013-2014 season.

The chart:

I then found the player's projected win shares (based on points and the graph's trendline) and looked at the players who most under or over achieved their win share projection. Perhaps unsurprisingly, high scorers on bad teams top the list. The top stat (or points anyways) stuffer: Tony Wroten!

Leading Stuffers - (most underachieved projection)

1. Tony Wroten -121.52%
2. Josh Smith -83.08%
3. Michael Carter -77.62%
4. Victor Oladipo -75.81%
5. Evan Turner -74.785
6. Dion Waiters -70.5%
7. Brandon Knight -58.17%
8. Jamal Crawford -57.77%
9. Nick Young -55.71%
10. Jeff Green -55.06%


Leading Anti-Stuffers (most overachieved projection)

1. Joakim Noah +139.98%
2. Robin Lopez +139.87%
3. Chris Paul +105.47%
4. Andre Drummond +86.96%
5. Terrence Jones +80.1%
6. Jonas Valanciunas +66.77
7. Marcin Gortat +58.74%
8. Mike Dunleavy +58.14%
9. Nicolas Batum +54.39%
10. Jose Calderon +54.34%


What do you think? Let me know if I committed any mathematical heresies. If I wanted to do all "all box score stats" comparison, what should I use instead of just points?

Kevin Love BTW, +20.9% over his projection (31st best of the 103).

WinShares includes stats, so it's no perfect for this analysis. Better to use RAPM, which is completely stat-free. Here's 14-year RAPM http://stats-for-the-nba.appspot.com/ratings/14y.html Sample size is an issue with that stat, so using more years leads to more accurate results

You could compare this to points, NBA Efficiency, PER etc.

Like the idea, but yeah, have to use +/- stats on this. Win Shares make Reggie Miller look like a stat stuffer, and he's the absolute opposite of it.

I think RAPM vs points and RAPM vs PER would be good things to try.
