Preseason prepping for 2019-20

I'm in the process of resetting all of the various DHD/RotoGuru Hoops reporting for the 2019-20 NBA season

As of today, I have tentative working versions of the following:

  • Sortable Stats, with DFS salary data for FanDuel, DraftKings, and Yahoo DFS. Note that I am only capturing salary data for the "Classic" format with the full daily slate of games. I will not be capturing salary data for single-game formats. Note that if you choose the trailing 7, 15, or 30 day periods, preseason games will be included. If you select "full season", preseason games will be excluded. (So if you want to see any data prior to the start of the season, don't select "full season".)
  • Game-by-game player histories for the current season (including preseason). From this page, you can also drill back to prior year histories.
  • Daily point recaps are now provided for preseason games. DFS salaries are not shown for preseason games, and some anomalies will be present for any game that includes a non-NBA team.
As in the past several years, I will be producing the premium NBA master data file. This will hopefully be available by Wednesday, October 23. The file will be provided for free for at least the first four weeks of the NBA season. Subscription details will be announced sometime in November. (Remember that a separate subscription is required for each NBA season.)

The Stat Summarizer will not be updated for 2019-20 until sometime after the start of the regular season. Stay tuned for further announcements.

As always, if you notice anything that looks to be incorrect, please send an email to

Plus VMI's vs Minus VMI's in Basketball

Today is probably a good day to mention something I've begun to notice in the NBA as related to the VMI. On Tuesday night Golden State went ballistic on the Denver Nuggets The Warriors set NBA records.

This points out two, maybe three things I've stated in this website, one (at least) that I'm going to need to change. It also pointed out one thing I'll keep without changing.

The Warriors came into Denver from their sea level location and sported a Plus 21.59 VMI. That means they were used to launching the ball with additional power by about 4 inches more than they needed to use in Denver. The adjustment normally means that accuracy in shooting should suffer like it did in October when they last visited Denver and shot only 24.1% three pointers.

Not only did the Warriors kill the Nuggets from every distance and angle, they shot 53.8% from downtown.

The thing I've been noticing lately that appears to be incorrect is this:

I have stated that it matters not whether a team is a plus VMI or a minus VMI, the fact they need to adjust should return similar results. I now believe that is a wrong assessment in the NBA. It is beginning to appear that visiting teams to Denver, Utah, Phoenix, Atlanta and Minnesota sporting a higher than normal Plus VMI, have an easier time adjusting to accuracy than teams leaving those arenas and traveling to sea level. A team leaving a higher altitude location would naturally sport a high Minus VMI and their normal thrust would leave the ball a few inches short.

The data is showing that being able to shoot further in a more relaxed state of being while arriving in Denver and other higher elevations is returning a little better results than the opposite situation. That is; it is better to be in the plus VMI, than the minus VMI.

Something that appears to be wrong, may be only a temporary issue:

Recently, I wrote that the three-point percentages in all the higher VMI Ranges had fallen below those in the low VMI Ranges. With the Warriors' very high shooting number and percent on Tuesday, the range (probably temporarily) exceeds the shooting percent of the low VMI ranges.

I will make changes to the text in our website as soon as I feel comfortable that these issues are not just temporary.
