NBA’s best clutch shooters.

This is why the Nets are scheduled to pay Johnson some $70 million for the final three years of his contract.

Based on his clutch genes, Johnson and Game 7s seemed as perfect a pair as Junior’s cheesecake and Flatbush Avenue, so you figured the Nets were in good hands last night.

Johnson, after all, had made all those game-winning or game-tying shots this season to help get the Nets to last night: Game 7 in their new building with their fans poised to explode in one of the most important games in franchise history.

So Johnson picked a horrendous time to play his worst game in a Nets uniform — six points on 2-of-14 shooting (1-of-9 from 3-point range) — in a sobering season-ending 99-93 loss to the Bulls.

Johnson did not score a single point in the first half, missing all five of his shots to go with two turnovers as his team spun out of control, falling behind the depleted Bulls by 17 points at the intermission.

Asked whether, considering the stakes and circumstances, he ever had experienced a more disappointing and frustrating performance, Johnson could not come up with one.

“It happens,’’ he said quietly, standing in front of his locker. “Unfortunately it had to be Game 7.’’

Make no mistake, though, without Johnson, who entered the game averaging 15 points on 41.6-percent shooting in the playoffs, the Nets would not have gotten as far as they did.

Without what Johnson brought to the team, the scheduled Rihanna concert would have taken place at Barclays Center last night, not Game 7 with a berth in the Eastern Conference semifinals on the line.

Nets interim head coach P.J. Carlesimo pinned Johnson’s struggles on the plantar fasciitis in his left foot he has been battling and the Chicago defense.
