If I had to ask someone else to make this decision for me and were given the choice between a) making a decision based on one relatively simple statistical rule or b) a professional making a gut call based on untold hours of practice, experience and situation specific factors which we are almost completely unaware of, I'm going to go with b every single time. The suggestion that we somehow know better than he did what decision to make is very difficult to defend in my opinion.
BTW, I don't really understand the stat you quoted. Any chance you could explain it in a bit more detail?
Speaking about the stats specifically though, I'd be interested to see what the actual measured statistical difference is between laying up from the distance he did, and choosing to go for it instead?
