Dave Hopla, a Washington Wizards assistant, is a 6-foot bundle of energy with graying hair.
He also can put the basketball in the hoop, over and over and over again.
He has two notebooks that he takes everywhere — a green, leatherbound one to chart his workouts and a black-and-white composition book to chart his shooting at speaking engagements.
Hopla can tell you, for example, that he made 99.2 percent of his free throws (11,093 out of 11,183) and 92.5 percent of his college-distance 3-pointers (260 out of 281) while delivering lectures in 2007.
He can tell you he once made 1,234 free throws in a row. His personal record for consecutive N.B.A. 3-pointers is 78.
He tells players it is not enough to try to make every shot. They should try to swish every shot.
