Steph Curry probably enjoys just being on a basketball court, even playing against people of much lower skill level. No reason he can't still work on perfecting his jumpshot for himself, even if it's only me guarding him. Lots of people practice shots by themselves.

I'm speculating here, but I think people who don't enjoy it on some level usually don't make it to that highest level in sport. Every top-level sportsman I can think of looks like they enjoy it.
