My reply is to the group talking about basketball metrics, not a response to you personally or in particular. I just wanted to chime in and the conversation has moved a little from this.
I find this basketball stat discussion super interesting. It's really really hard to quantify certain things in sports like football or basketball. Let me give you an example from my daughter's college game last night. She's averaging about 20 a night for her D3 team (on about 13 FGA, so she's a very efficient scorer, especially for this level). There's a play late in the game, a close game. She's on the floor with a couple of kids who aren't very good (injuries and foul trouble has forced some deep bench players to get significant minutes). She is on the right wing and drives into the lane using her left hand (she's a lefty). The defense collapses. She's got a nice little lefty hook, but to shoot it would be in amongst all the traffic converging on her. Definitely a tough, contested shot. But she's a good scorer as I mentioned. But the player the D leaves open is one of these bench-type players wide open at the top of the key. My daughter's basketball instincts kick in and she dishes perfectly to the wide open player who promptly...throws up an air ball out of bounds.
The alternative, in that moment, would be for my daughter to take a contested shot, with a low probability of being made. But, I contend, still a higher probability than her wide open bench-level teammate making a three. From a general basketball approach, the pass to the wide open teammate for a free look at a three is the right play, as opposed to a challenged shot in traffic. But it was to a bad player, so even then the odds weren't great that she would make it.
So in this particular situation, the "right" play, in my mind, was for my daughter to take the contested shot. It would have lowered her shooting percentage most likely, and the basketball metrics would have graded that a bad play, but given which teammate was open, I still think I'd rather her take the contested shot than give it up for an almost certain miss by this particular teammate.
How in the world would basketball metrics determine whether my daughter made the right play or not? How would they determine whether her choice was a good one or bad one?
