APBRmetrics

Hi Folks,

I am using this formula to calculate team possessions.

Possessions= 0.5 x ((Tm FGA + 0.44 x Tm FTA - 1.07 x (Tm ORB / (Tm ORB + Opp DRB)) x (Tm FGA - Tm FGM) + Tm TOV) + (Opp FGA + 0.44 x Opp FTA - 1.07 x (Opp ORB / (Opp ORB + Tm DRB)) x (Opp FGA - Opp FGM) + Opp TOV))

My question is when I am entering Opp DRB and Tm DRB is that total DRB (Including team DRB) or just the Defensive rebounds assigned to the players?

Thanks for the help

Rachel

Some rebounds are TEAM rebounds, and arent counted as individual rebounds that are assigned to a specific player, therefore the sum of individual rebounds for a teams players never adds up to the team's TOTAL rebounds. If youre looking to calculate a teams possessions, Id go with a teams total # of REB's.

Are team rebounds always defensive rebounds? Is it true that team rebounds should be counted towards Tm DRB because I can't find any reference to that in Basketball on Paper? Also, if you look at a box score at basketball-reference, you won't find any mention of team rebounds and a pace calculation is based on sum of individual rebounds only.

I get the impression that a team shooting the first or non-last fta(s) automatically get a team offensive rebound but I prefer not to mess with them at all.

And what is your take on counting team rebounds towards Tm DRB in formula for team possession?

I didn't want to venture a guess; but for team possession, I guess I might split team rebounds into parts towards Tm DRB and Tm ORB in proportion to the player level data off. / def. split.


Rachel, what are you using team possessions for and how does it look when you calculate it the various different ways?
