Eminently likeable Greek-American actor John Stamos had two problems when he took on the role of basketball coach Marvyn Korn at an elite girls high school for the Disney + new TV show Big Shot.

The coach is not a nice guy and Stamos said he didn't know the first thing about basketball because he was in the marching band in high school in California and found the role tougher than playing in ER.

I never played sports, I didn’t watch sports,” Stamos told the New York Post.  “It was harder for me to learn basketball lingo than medical lingo when I was on ‘ER’ playing a doctor, I’m not kidding.”

He learned from the best though, the NBA Logo and Hall of Famer, the legendary Los Angeles Lakers player and executive Jerry West, who taught him. “He told me it’s called ‘practice,’ not ‘rehearsal,’” quipped Stamos.

His character finds out coaching talented and tough-minded girls isn't easy either because he meets with resistance from them. “It was nothing like anything I had ever done, and it was nothing like me,” said Stamos. “He has no charm.”
