I understand, but FG% does have its place. When judging a player's worth, you must look at numerous stats. Also, stats never tell the whole story.
I like to think of FG% as a marker for how good and smart a shooter is. A good shooter could have a low percentage if he does not take good shots. A bad shooter could have a high FG% if he is taking good shots. A dumb shooter cannot have a high FG% unless he is just lights out on all shots. A smart shooter cannot have a low FG% unless he just cannot shoot.
