In 16 NBA seasons, Rasheed Wallace was consistently the loudest voice in any building. While becoming a four-time All-Star and the league’s all-time leader in technical fouls, Wallace’s personality was even more dominant than his play.

On Sunday, coach David Fizdale invited Wallace — who played the final 21 games of his career with the Knicks and memorably starred for the Pistons when current Knicks general manager Scott Perry worked in Detroit’s front office — to work with the Knicks’ big men at practice, hoping Wallace’s confidence and ferocity would rub off on soft-spoken rookie Mitchell Robinson.

Wallace, who spent one season as an assistant coach with the Pistons, is expected to work more with the Knicks this week.

“I just thought he’d be great to have him come visit with our big guys. He’s a technician from an understanding fundamentals standpoint, understanding the big-man position,” Fizdale said. “I just think he’s a great voice to have in the gym, a nice change of voice. He’s a guy that could help Mitchell understand how to use his voice.

“I’m connecting with a lot of guys from our past to bring as many influences around these guys as we can.”

While Patrick Ewing and Chris Bosh previously spoke with the young team — Fizdale plans to bring in Chauncey Billups soon, too — Wallace was an active participant in practice, running drills and yelling at the “lollygagging” big men.

Wallace spent extra time after practice with Robinson, with the pair having previously developed a relationship through Wallace’s college teammate Shammond Williams, who is Robinson’s godfather.

“He was an NBA legend, so actually getting to work with him, it kind of felt great,” said Robinson, who joined the starting lineup in Friday’s loss to Golden State. “He helped me out with pointers on the baseline as in the dunker’s spot, where to flash to, get up on my screen-and-rolls, too.

“He pushed me to talk more on defense. I have a tendency to be a little quiet, and him, he brings it up for me.”

Emmanuel Mudiay (ankle) practiced Sunday, and is listed as probable for Monday’s game against the Nets. But even though the guard is now healthy enough to make his season debut, it doesn’t mean Fizdale will be ready to put him on the court.

“I don’t know how soon I’m gonna do it, but at some point I’m gonna want to take a look at him, and see how he looks,” Fizdale said. “He really helps our pace. I think he’s our best at getting guys the ball where they need it. It’s just a matter of finding the right time to do it.”

Courtney Lee (neck) will again be out, along with Kevin Knox (ankle), though Fizdale noted the rookie continues making progress.

“He’s still out right now, but he’s getting a lot better,” Fizdale said of Knox. “He’s getting healthy. He’s been doing some conditioning stuff, some light things on the court. He’s been doing some shooting drills, things like that, so he’s not far away.”
