Well batting averages flaws are pretty easy to point out.
"When a hitter draws a walk, batting average acts like nothing happened. But OBP not only shows the players batting average, but also gives them credit for every time they reached base, regardless if it was a hit by pitch, a walk, etc"
Everyone can understand very quickly why OBP would be more valuable than AVG. It tells more.
But Slugging percentage also tells you more than batting average because a single isn't worth the same as a home run, or a double, or a triple. And a double isn't worth as much as a home run, or a triple. But batting average treats each extra base hit as the exact same as a single. And we know that isn't right. Because clearly a home run is worth more to a team than a single.
These are both pretty damn obvious, and anyone that choses to ignore this....is well....woefully ignorant. This is information that should be pretty well known by now to anyone that follows baseball even just a little. Even my 8 year old nephew knows the difference (it was discussed this weekend).
And we also know that OBP and Slugging have their flaws as well, but not to the extent of batting average. But that's a lot more typing than I feel like doing now, and I know that you (Bos Sports4Life) already know all of it
ESPN grabs the attention of the casual baseball fan. Or the fan that likes other sports maybe more than baseball. They give you the brief information about whatever is topical in baseball at that time, and that's it. And most people, that is really all they want.
I have seen some advanced stats displayed on ESPN, but I know it isn't shown much, or even talked about much.
