The made up strongman events such as the truck pull, tires, kegs, and stones are essentially tests of brute strength with little carry over to any sport but strongman...
This guy fails to realize that every sport is "made up."
Seriously, who ever thought of taking a long metal pole, loading the ends with iron, then flinging it over your head in a single motion? It's really an arbitrary motion. It's a good one, but just because it's been around for a while doesn't mean that it wasn't "made up" somewhere along the line.
