She couldn't be more correct (although I found the f-bomb to be unnecessary).
GOAT conversations don't grow the sport. They don't get people off the couch and out for a run. They do very little, if anything, to increase viewership of major races. They don't increase the prize pools or attract new sponsors.
Presenting the audience with stories they can relate to, or giving them living examples of what they can aspire to be will get more people to run, to watch, to consume running media of all types, and sponsors will want to get in front of them.
A father dragging his disabled son through an Ironman will get more people up and out the door and will drive more eyes to the annually televised centerpiece of the sport than will the first man to break 8 hours.
