but you could have atrocious free throws and still hit 30% from the line, with high atrocious you made in average 20-25% i would say.
But rebounds are calculated a different way then free throw, because it is a team skill ...
So my player with atrocious inside shot could make layers, because i got an solid inside attack which helps everyplayer on court to finish inside. In free throw it's a think for the single player alone.
