i think from memory that the BB-Game analyzer doesn't treat's these as open shots.
There is in-game text that says ' gets open in the corner' which is obviously open
But then there is game text such as:
"has plenty of time to set-up, and shoots from near the foul line"
Is that an open shot?
What about this one?
"C. Querido (A) finds A. Khare (A) in space. A. Khare (A) attempts a jump-shot from the wing" - Is that open?
So the BB-Game Analyzer has a set of rules for these things, which you can analyse. I recommend using that tool to analyse ur games, as opposed to guessing what each thing represents.
