Founder and president of Impact Basketball Joe Abunassar thinks Kawhi Leonard’s jumpshot is a simple fix.

He says the ball rotation and footwork is fine. In drills, he tried to shorten his stroke and get the basketball on his fingertips and out of his huge hands.

It’s likely something the Spurs tweaked this week, too. Abunassar thinks it’s easily correctable when Leonard returns to work with him in a few weeks.

“It’s just a repetition thing,” Abunassar said.

But repetition isn’t always fun. Leonard turned 20 on Wednesday. How many guys that age, finally free of school and with some money, really want to spend summer sweating in a gym?

Leonard appears to be one. “If his workout was scheduled for 9 a.m.,” Abunassar said, “then he was in at 7:45 a.m.”

Sometimes he stayed until 11:30 p.m. Sometimes they had to tell him he had to leave.

“Kawhi is one of the most focused and serious,” Abunassar said, “I’ve ever had.”
