Why is a jump shot a tactic in basketball?

Answer 1

Often, jump shooters are accurate free throw shooters and percentages play in the jump shooters favor at the free throw line. For example, a good jump shooter might shoot 46-50% from the field, but at the free throw line this increases to 80% and higher (i.e. ~30% increase in getting 2 or 3 points). One exception would be if the jump shooter has a clear layup or dunk (virtually 100% success). In this case, fouling and preventing the basket is worth it.

Answer 2

Because you're an idiot.
