It is irrelevant whether you are trying to reach casual fans or supposedly hardcore fans. The worst possible thing you can do is dumb the sport down for a perceived audience of American housewives (a demographic that perhaps doesn’t even exist in reality anymore as an economic force.)
Regardless of the sport, fans (casual and otherwise) would like to be flattered and challenged with the language of the sport. What they DON’T need is to be patronized by paternalistic announcers that treat them like idiots. Can you imagine an NFL broadcast that says “now these men are going to THROW the ball, and if one catches it past 10 yards, that will allow them to run more plays on the offense.” But we get spoken to in this tone in the track world regularly.
As has been mentioned, Phil Liggett doesn’t talk to viewers this way. But the producers of track and field in the USA down through the years have passed on a received wisdom of infantilizing the audience. How’s that worked out for them? It’s marginalized the sport, and made their job worth less. (And when people in a position to do something about this had their opportunity over the last 30 years, they considered their self interest first rather than speaking up. I’m looking at YOU, Dwight Stones, et. al.)
So the solution is to follow both the Kentucky Derby model and the Tour de France model. The former focuses on competition, pageantry, and tradition rather than records. The latter focuses on competition, pageantry, tradition, and passionate presentation that challenges the viewer.
This isn’t as complicated as people are making it seem. I’m not saying it’s easy, but there’s a formula for relative success and the obtuse among us are refusing to acknowledge it.
