Many are triggered by the concept that the biggest, best, most athletic play soccer in other countries. Just look at heavyweight in the US. Gable Steveson is the most athletic and best American heavyweight I have ever seen. There are countless more athletic guys in college football locker rooms without a shot at the NFL.
Wrestling is a skill. Athleticism can matter, but I really don't think it's as important as many believe. To be good at anything, an internal desire is the most important thing. That's why I am spending my kids youth simply making sure they have fun doing sports, whether it's from goofing off and being silly, making a friend, getting a happy meal after practice, or praising them for doing something the right way. The whole point is to make them want to come back, and if they keep doing it for a while, they will get better. We can worry about what success looks like for them later.
