It's definitely an interesting story, but I think even more interesting is the reaction to it. It seems like people really love the status quo.
What would the reaction be if shoe companies or USATF poured these resources into their individual athletes? Would we applaud it because that's the way it has always been done--that athletes are sponsored by shoe companies?
A cynical take on the status quo is that the shoe companies are only sponsoring athletes because they think it might benefit their bottom line. They support as little as they can to turn the athletes into a walking (running?) billboard.
But here we have a family pouring a lot of their own resources into an athlete without expecting some kind of financial return, and many commenters take issue with the idea that Hoey's family is supporting him. In a perfect world, every athlete would have the resources to do what the Hoeys have done, but this isn't a perfect world, and it never will be. To have issue with a family that is chasing a dream in an imperfect world seems misguided to me.
As for the idea that his improvement can only be attributed to PEDs, well, when he gets popped, you can come back here and gloat, and prove that you were right. We're back to the status quo, though: "You ran 1:47 in 2018 and stagnated? There's no way you can run 1:43 seven years later. You can only progress a certain amount of time each year or you're using PEDs. That's what most other people have done."
TL;DR: The story is interesting, but the reaction says more. We want our athletes to improve, but only by a certain amount in a certain time frame. We want our athletes to be supported and given great resources, but only by USATF and shoe companies and only up to a certain amount.
If you have an issue with how much the Hoey family spends on supporting their children, tell me how much would be okay for them to spend. What should be the limit?
