Come on down, Alize Johnson!

It’s your turn to star on the beloved game of “Name the next unheralded Nets player who comes up big.” Just like previous contestant Nic Claxton.

After playing a total of less than five minutes in the previous five games, including three in which he never got off the bench, Johnson provided an invaluable lift Monday against the Knicks. Quite simply, even with Kyrie Irving’s 40-point outburst, the Nets would not have won without Johnson’s 12 points and seven rebounds in 17 minutes — and a hunger that veteran teammates find infectious.

“From the moment that he got here, that’s how he’s been,” guard Joe Harris said. “Even in his practice sessions, he doesn’t back down from anybody, is ultra-aggressive on both ends of the court. I’m glad that he got an opportunity.”

Nets coach Steve Nash indicated that Johnson would have played more minutes if not for James Harden’s hamstring strain forcing Chris Chiozza into a more prominent ball-handling role.

Johnson’s second 10-day contract expires after the next two games, at which point the Nets either have to sign him for the rest of the season or let him walk away — perhaps using the roster spot on another point guard while Harden is out for at least 10 days.

Maybe the 24-year-old Missouri State product’s performance against the Knicks — “His versatility could help us, and he was great,” Nash said — combined with his 23-point, 15-rebound performance in a blowout loss to the Jazz opened eyes around the league if he isn’t with the Nets.

It’s going to take more than a little competition to get forward Jeff Green down after a journeyman career bringing him to his 10th team in 14 seasons. The Nets signed Blake Griffin and LaMarcus Aldridge in March, creating a frontcourt logjam that only could mean a reduced role for Green.

Good luck justifying benching Green after he averaged 21.7 points and 4.3 rebounds over the past three games. His offensive rebound and tie-breaking free throws were the difference in the final seconds against the Knicks.

“He has sort of seen and done it all in his tenure in the NBA, and it’s no different with us,” Harris said. “There are some nights where it might not look like he’s showing up on the stat sheet, but he does all the little stuff all the time. And then when we need him to come up for us offensively, he typically does.”

The Knicks ran a second defender at Irving’s face in the final minutes of the fourth quarter and he committed one costly turnover and nearly a second. That’s not a new scheme just invented to suddenly befuddle the All-Star.

“I’ve seen as many defenses as you can imagine, since I’ve been 11 years old,” Irving said. “It’s a very simple game at that point. They take two on the ball, and then we play four-on-three on the backside.”
