Although, thinking about it more, you could say, the difference between
Brock Purdy and all the other 6 ft 1 220 lb males with good shoulder sockets in the world is the mental side, not the physical, and therefore that's why he's in the nfl, and they aren't.
I guess then you'd also have to factor in the variable of opportunity. There may be some people in parts of the world that if they had Purdy's access to various things by way of living in america, etc, they might have been able to make it over him. But that's a whole other discussion. Okay I'll try to be done now 🙂
