In 1991, Toronto's team rebound differential was 44.3-41.5, so they
were a good rebounding team. Detroit averaged 45.0-44.5, just above
average, and with more rebounds around.
Saying there were 85.8 rpg in Toronto and 89.5 rpg in Detroit would
imply that one's rebounds per minute should be higher in Detroit.
A further distinction might be made between rebounds gathered by your
own team vs. opponents. I have come to believe in scaling only the
opponents' rebound totals.
In this case, considering total rebounds gives Corliss a per-36 rate
in Toronto of 5.75, and 7.29 in Detroit.
Considering only opponent rpg yields a change from 5.94 to 7.33.
The difference is now less dramatic ( +23% rather than +27%)
It's my belief that making this adjustment would tend to smooth the
majority of transitions from one team to another, for most players.
And I would consider this evidence that it's a viable adjustment.
In this case, the Pistons apparently needed scoring even more than
they needed rebounding, and this is what the guy does (did) well.
Even his turnovers dropped about 20%, despite the increased offense.
Such across-the-board improvement can never be predicted by mere
About 10 years ago, I did look at Rodman's effect on his teammates.
I'm sure it was on paper and now lost; not sure how I did it, but it
seemed clear he was depriving teammates of rebounds, once he decided
to be a 'specialist'.
