From what I count:
ESV Laim - 32 out of 92 which makes 60 to rebound plus 2 free throw missed that could be potential rebounds (if the last free throw).
Vitoria Devils - 32 out of 83 which makes 51 rebounds plus 4 potential free throws.
In total there would be 117 potential rebounds but there were only 111. It would be easy to consider just the free throws as not rebound but we should also take into account the last second shots (that do not have rebound).
Anyway, the diference between both teams is less than 10 rebounds!
Now each position:
ESV laim Vs Vitoria Devils
PG SG SF PF C
7 - 1 3-5 10-13 15-19 14-24
Only on the PG position (which I suppose has a minor effect on the rebound rating) the ESV Laim where superior. And yes, I know that some players out there played more than one position but in general this is what happen.
So I don't really understand the ratings... (ESV Laim went with a 3-2 defense!) even with less available rebounds, ESV Laim should have been worst or the same in terms of ratings for rebound!
