DRBL-P

Possession-side diagnostic: how DRBL’s play-by-play attribution looks versus the R1 baseline. Parent of DRBL-O and DRBL-D, not a piece you add with LN and B to rebuild DRBL/100.

What it teaches

  • How the “what happened on possessions” slice looks relative to expectation.
  • The parent view that Offense (DRBL-O) and Defense (DRBL-D) split.
  • One of three context lenses (P, LN, B); they don’t add into the main ranking.

What it doesn't

  • The same thing as DRBL/100, or DRBL/100 when added to LN and B.
  • A tracking / off-ball camera metric.
  • Traditional WAR or replacement wins.

Upsides

  • The closest look at the possession credit behind DRBL.
  • O/D halves give a readable offense vs defense split underneath.
  • Helps explain disagreements without changing the public rank.

Downsides

  • Easy to misuse as a second ranking total.
  • Adding P + LN + B invents a false overall number.
  • Still not a causal “replace this player” estimate.

How to apply it

  • Open advanced disclosure when DRBL/100 needs a possession-side check.
  • Read O and D as splits of P, not of DRBL/100.
  • Never treat P + LN + B as the “true” ability rate.
