Daniel Artest Metta World Peace’s brother who had a brief professional career told The Post the Knicks were missing a certain element last season — “a goon.’’ He feels his brother can fill the bill.

The Knicks got beat — and beat up — by the Pacers last May in the playoffs. And they signed World Peace partly with the rugged Pacers in mind.

“They’ve got a good team but they never had that goon — that defensive goon last season’’ Daniel told The Post yesterday from his home in Indianapolis. “Someone that’s not afraid. If Ron was on the team they would have gotten past the Pacers.’’

The former Ron Artest is renowned as one of the league’s all-time most physical players and that has gotten him in trouble. He was suspended 73 games for the infamous “Malice at the Palace” brawl when he played for Indiana. He’d probably like to shed some of that image.

“I’m not worried [he’s washed up]’’ Daniel said. “It’s all about heart. The way Ron plays he will help the Knicks out the way he plays defense and take pressure off Carmelo [Anthony] [who] won’t have to guard the best forward guy anymore. [World Peace] can guard the power forward. He held a lot of power forwards like Zach Randolph David West and LaMarcus [Aldridge] last season way below their scoring average. He’s still very strong and has a lot of game left.’’

Daniel Artest doesn’t mince words when he describes his brother’s physical game. Daniel wore No. 51 at South Nevada Community College in honor of his father who wore the number in high school at Long Island City. Daniel didn’t play high school ball because he periodically dropped out.
