Posted: Thu Sep 10, 2009 10:22 am Post subject: Second-chance points and other new stuff on hoopnumbers |
|
|
I've made some additions to http://hoopnumbers.com, including (for each player) the average number of second-chance points scored by the team following that player's missed field goals. This stat is analogous to the Miss Offensive Rebound Rate numbers which some people took an interest in before (and which is still available, with a slight tweak) while also tracking whether the team ultimately scored. That depends on the general offensive efficiency of the team, of course, but it also should depend on whether the player's misses generate lots of easy putbacks vs. longer offensive rebounds where the team has to set up their half court offense again.
My apologies for not setting up an RSS feed yet. If anyone can point me to a link that makes it easy to do that, I would be appreciative.
Note that the Miss Offensive Rebound Rate (MORR) numbers now include team offensive rebounds, unlike before, so they are a bit different. I thought about it and decided that if a particular player consistently has more misses than normal go out of bounds off of the other team then there's no reason to ignore this.
Another new stuff:
- League wide rankings for all stats
- For the outlet passing stat (Fast Break Trigger Rate, the probability that the team scores on a fast break if a certain guy gets the defensive rebound) I also have the FBTR for the team when the player is on the floor but not the rebounder. This way we can check if a low FBTR is because the team didn't run much while the guy was on the floor. That's usually not the case, though. The team FBTR is usually normal, so the player's FBTR does seem largely to reflect his own characteristics.
- Team totals for the second chance points and assisted % stats.
- Overall team totals and averages for two point and three point attempts. Unsurprisingly, the MORRs and second chance points rates per *miss* are higher for two point misses than for three point misses for almost every team. However, since three pointers are missed so much more often, the second chance points per *attempt* is sometimes higher for three pointers than it is for two pointers (I haven't done a careful analysis of this yet, though). |

Really like the Team by Team sort or League wide. This is great.
I really like the Two point shooter and Three point shooter on each team.
Can I suggest you use slightly shorter heading labels, and include a glossary - that allows you a little more space to say exactly what the statistic is, and allows you to fit more than about 5 numbers in a table (If I was being Really greedy I'd also ask if we can sort by other columns too but I can do that in Excel). |

Its interesting to see how the Sacramento Kings appear to have been far and away the best team in the league at scoring off of offensive rebounds (if you sort through the league wide stats you'll see that all the players most likely to have seen points result from their missed shots that were rebounded were all Sacramento Kings). |

Thanks for pointing this out. This is actually an issue I was aware of but forgot to make note of on the site until now. I am using the ESPN play-by-play transcripts as a data source, and for some weird reason there were no team rebounds recorded in the play-by-play for the Kings last season. It's really strange, because it's not as if no team rebounds were recorded for either team for games played in Sacramento. There are no team rebounds for the Kings for any of the 82 games they played.
Since my numbers included team offensive rebounds (not the meaningless ones which are credited when a player misses the first of 2 free throws, but the "live ball" team offensive rebounds), the offensive rebound numbers for the Kings were depressed and the points-per-offensive-rebound numbers were inflated. Sorry about. I've made a note of the issue in my writeup and replaced the invalid numbers with "N/A". |
