The prime example I could think of is underhand (or "granny" style) free-throw shooting, most famously practiced by Rick Barry in the '60s and '70s.
My buddy argued for the merits of the overhand shot:
Also --- I'd argue shooting an overhand (or whatever you call it, traditional) free throw is good because of the halo effect.I can see his point, although Discover magazine and others disagree. Remaining agnostic, I asked: "Did you give underhand a fair shake when you were a kid, weighing the pros and cons and eventually deciding to abandon it?" It was a loaded question, of course. No kid gives underhand shooting the time of day, even if the (potentially) minor advantage might have scored him a few more points, won him a few more games, and so on.
At the free throw line a struggling shooter can build confidence in his shooting motion by taking easy shots in the overhand motion. So take a few free throws, get your shot back, and suddenly you're swishing three-pointers again.
By the way, I'm not the first person to make this observation.
