i'm having an issue w/ FTR. this factor seems to be dependent on TO% and OR%.
higher TO% -> less FGA -> higher FTR
higher OR% -> more FGA -> lower FTR
shouldn't the 4 factors be independent? shouldn't the FTR factor be more like FTA%?
edit: not thinking here. of course it's still independent. whether or not you get an extra possession from an OR or lose one from a TO you still have a chance to shoot FT vs FG.
IMO they are all good independent measures, but no doubt they have some dependence on each other. All of the scenarios you mention could be true, and I'd say one reason our FT rate is lower this year is b/c we have a higher TO% than last year. It makes sense that a wasted possession would mean a wasted opportunity to get a FTA or a FGA and thus also an OR.
And I'm not sure what you meant by "shouldn't the FTR factor be more like FTA%?" b/c essentially that is what it is.
