THE CRUCIFIX: Cato: Wood isn't thrilled w/ his role...Will depart in the summer

[DanSchwartzgan]

But there are four other players WITH Wood everytime he plays...it is not his fault if the bench players lay an egg when he is in. So on/off is the only truly helpful metric here because it rates him relative to other team options. 

And, since Wood has only played half of the team's minutes this season, half of his net number comes from the quality of player who subs in for him.  Maxi, Dorian and McGee have not been good in On-minus-Off.  Their lack of effectiveness actually helps Wood's On-minus-Off by comparison.  But, it doesn't tell you if Wood is good in isolation.  It tells you Wood is good compared to.  

BTW, there are four other players WITH Wood in his On-minus-Off number (the On part) AND there are four other players WITH Maxi/DFS/McGee/Powell when Wood is sitting (the Off part).  Neither number escapes the issue you are trying to assign to On Court.
