ok....now here is one way to look at it:
in baseball i could play right field with some form of ability, heck even with a few at bats you might at least draw contact.
In basketball, i would at least make them guard me, if they didnt I would surely score from deep.
Football same thing... the avergage male athlete could run passing routes and if they decided to not cover me I would at least catch a pass.
Team sports with multiple positions could be played and you could at least pass and dribble or go get a grounder and throw it to someone else.
Even golf, i can at least par holes in which pros par holes. you arent playing the player, you are playing the course.
Its the individual head to head sports especially contact sports where you get crushed, injured or you cant do one thing to compete.
