Starting Five: Mirza turning up the heat

EAST RUTHERFORD, N.J. -- Brooklyn Nets stretch forward Mirza Teletovic was so good on Saturday night that even actor Jake Gyllenhaal was impressed.

After Teletovic knocked down a fadeaway 3-pointer over LeBron James in the third quarter -- one of three triples he hit during the quarter -- Gyllenhaal, seating courtside next to Jay Z, turned to the hip hop mogul and reacted by shrugging his shoulders.

Nothing needed to be said. Teletovic’s play spoke for itself.

The Bosnian sharpshooter had nine of his 12 points in the third, helping the Nets claim a 104-90 victory over the Heat in Game 3 of the Eastern Conference semifinals at Barclays Center.

In his last two games, Teletovic has shot 10-for-16 from beyond the arc (62.5 percent). Remember: in his previous eight games, he’d shot just 25.7 percent (9-for-35).

“There’s no time for mistakes. There’s no time for errors,” Teletovic said. “It’s the playoffs. You’ve got to bring it.”

During this series, Teletovic has guarded LeBron James and also played center in coach Jason Kidd’s super small-ball lineups. No big deal or anything.

“I think the biggest confidence I get is from my teammates,” Teletovic said. “They get me involved in the game and try to find me shots and give me a lot of confidence.”

If you recall, Teletovic played just one minute in the playoffs last season.

“It was tough,” he said. “But I had a lot of patience, doing what I could to learn from the games.”

The Nets wouldn’t be where they are right now without Teletovic, whose best moment this season came when he smirked at James following a regular-season altercation with the King.

“When you talk about the Miami Heat, they’re the two-time champs,” Teletovic said. “And you always wanna bring your ‘A’ game against the champions.”
