I'd like to see the game in question. Somehow I doubt there was anything other than kids playing basketball and the losing team giving it their all the whole time. Basketball games usually don't make it to 94-4 without breaking into a fight if any malice was involved. Besides, a quick google search reveals this is not the first time a blowout like this happened. Why all of a sudden a coach is punished now if that's something not known to be done before? Sounds to me like someone's mommy or daddy is on the school board.
Well, for the same reason that the first few times various posters brought up concerns about trans athletes, the threads were a little interesting, and the second time they were brought up a few years later from the same court they were fairly annoying, and then when they were brought up this last year or so by the same folks, they were grating and everyone could clearly recognize the orientation of the position.
One point is an anomaly, two points gives a suggestion of effect, three points gives a clear trend, and once a bad trend has been identified, any additional action on that trend requires response.
In short it takes a few instances to really generate a clear-enough case.
