But why is there an absence of specific information? A team would be very stupid if they didn't keep track of their specific results as well as their opponents results. There is no need to go to league averages. My point was using league averages gives you incorrect information that is too generic because there are too many specific factors that affect that math. Each team should use their specific information (as well as current game information - injuries, tendencies seen that day, etc) to decide the best approach to win. Which may or may not be to go for two. There is no absolute mathematically proven answer but you have a better opportunity to be closer using team specific and game specific information to decide.That's as may be, but the default position, in the absence of specific information, should be to go for 2 there. If you then say, well, I'm going for 1 because we stink at 2-pointers, or the other team has an unusually great goal-line D, or some other reason, then you can make that argument. But usually you won't have enough information to know how much to stray from the averages with any certainty. The upshot is that most teams should go for 2 most of the time, and they should be questioned when they don't. The current state of affairs is the exact opposite.
