APBRmetrics

What stats do you expect to be tracked in future box score stats (SPM) or RPM? What do you want to be tracked?

For me I am looking forward to the following being tracked:
Charges (Charges to block ratio)
Offensive fouls drawn and committed
Split up turnovers of offensive players by live ball (steals) and dead ball turnovers
Blocks by distance form the basket
Dunks (Is this correlated to success in Plus/Minus?)
Deflections out of bounds
Assist credit split up by type of assist (Layups, Mid range, and 3 pt)
Split up Ball handling and bad pass turnovers for PG's
Adjust assists by teammates openness and FG% on Assist opportunities

In the mass consumption box score it will mostly be more sausage-made-from-numbers stuff like RAPM and WAR rather than raw data. Single number stats are much more 'accessible' to people and space is precious.

In general, we can expect the historical trend of caring about what happens to the ball and ignoring everything else to continue. They'll probably publish dribble counts before picks set, transition hustle, or even box out stats for rebounding.

I expect one of the big changes in 5 years is rebounders rated in a very different, more complex way. Raw rebounds per game is no better than raw points per game. Spacing will also be quantified

Well REB% is a much more useful stat to look at than raw RPG, but yeah tracking could bring loads of new, relevant data.

I use most of those things for my stats. Actually, I've tried all but one. And I'm pretty sure RPM already uses things like splitting up live ball steals with deadball turnovers.

There are some interesting things you can do with rebound plus/minus and, perhaps, box-outs in SportVU.

Spacing has been quantified a little already even before SportVU. But gravity and "openess" are being quantified now.

Do you have a list of things that you put in your stat? Based on your site, I only saw a few box score stats mixed with SportVU stats in your metric. What kind of effect did these things have on your metric (assists by area, blocks by distance, splitting turnovers) compared to having a generic assist, turnover, block value?

...

Wouldn't Ast opportunities * FG% = Assists?
It's not hard to estimate the % of a player's assists that are 3pt FG.

It's also not hard to estimate the % which are just home scorekeeper generosity. This is a big one, amounting last year to almost 1 Ast per home game for Kyrie Irving.
Dellavedova averaged 4.4 Ast/36 on the road and 6.3 at home. These are signicant discrepancies, and not justified by the Cavs' shooting better at home: They had 0.7 more FG/G at home, but 4.1 more Ast.
