Good post. I'll add another qualm about this imaginary statistic-the inherent biases from the scorekeeper keeping said imaginary stat. I'm fairly certain a certain "dirty ole nasty dawg" gets more leeway when making a potential assist that turns blown than a less favored member of the heels. Besides that, by its very nature the blown assist is a canard because two people watching the same game may not agree upon wether said assist ending in a blown should be categorized as such.
Statistics need to be objective, something which all scorekeepers can agree on. The blown assist by its very nature is subjective and as I've explained very vulnerable to biases.
If you actually want to know why that stat matters, here ya go:
1. Assists themselves, as
I've explained, are inherently subjective. Two different scorekeepers will often come up with different totals. Thus, since Assists are subjective, Blown Assists are no more so. Translation: it has the same level of validity.
2. By their nature, Assists are passes that directly lead to made FGs, whether it's say, an open 3, a shorter jumper, or layup. An open rhythm-3 off a pass for a college player is a 50%+ shot (more like 60 for good shooters), a shorter jumper better than that, a contested layup better than that, and an open layup should be 90-something.
3. Therefore, the Blown Assist metric concentrates on
how a team is finishing on high-percentage shots. That is a very telling number,
especially for an offense like ours that is predicated on getting high-percentage shots. Relying just on overall FG% does
not isolate that aspect --- Blown Assists do.
4. Since these are supposed to be high-percentage shots we should be converting more than we're missing. So if, for example, we total 15 Assists for a game (like we did Saturday) but blow 17 in just one half, that tells ya something about how we're finishing, and it certainly tells a lot about why we barely pulled out a win that should have been relatively easy.
So again, if you're actually interested in why that stat is valuable, well there's the explanation, and it's logical and completely open and shut. If, on the other hand, your real purpose is to simply attack me or my integrity then that is just rather sad.
