SAN FRANCISCO — Kristaps Porzingis had Knicks coaches place a black iron device inside the rim, making it smaller.
He spent half an hour after Monday’s practice as the last player on the court at the Olympic Club, working on his shot with Knicks assistant Dave Bliss. The device reduced his margin of error and forces him to put more arc on his shot.
“It helps for precision,’’ Porzingis said.
Porzingis’ shot hasn’t been too precise since December, as he’s shot 40 percent. It’s too late to impress the NBA’s coaches, whose All-Star reserve submissions were due Monday morning.
