A recent article I read indicated that officials are right about 94% of the time. That would seem to indicate they are better at their jobs than coaches or players.
Depends what you are counting. If "dribbles," then players probably get more than 94% done right. If "shots," then not.
As for refs, I assume you are counting actual "calls" they make, not "non-calls" (which I would consider worthy of measuring if we are really serious about evaluating refs). Tonight, I may try to keep count of how many actual calls they make in comparison with ones where I would be yelling at them for making the wrong call (or chuckling that we got away with one).
If I get to 19 without a bad call, then I will know to get ready.
