LeBron James' willingness to take games off for rest shows he's not as "tough" as Michael Jordan, according to Jordan's former Chicago Bulls teammate Dennis Rodman.

Rodman took the Cleveland Cavaliers star to task during an interview with CBS Sports that aired Tuesday, saying rest is proof that James is not at the same level as Jordan.

"You know what, LeBron's doing one thing that I always said that Michael Jordan never did," Rodman said. "He never rested. He played every game. LeBron has the position to do this now because they need him. The league needs him, and that's why he's doing all this crazy s--- now, like bitching and complaining and all this bulls---."

Rodman also said it has been "very easy" for James to succeed in today's NBA, comparing him to Jordan again by noting that the Bulls star "led the league in scoring 10 years in a row" (excluding his missed seasons to pursue a baseball career) when "that was hard" to do.

"Back then, when he was getting his ass whupped, I mean beat down every game, and then when he played against us [the Pistons], he said -- guess what -- 'I gotta go back in the gym,'" Rodman said of Jordan. "And he got tough. He got tough, and he got great. And greater. So that's it."

James has never played all 82 games in a season, and he has missed six of the Cavaliers' 78 games this season. Jordan played the full slate nine times in his career.

"You know what, LeBron's doing one thing that I always said that Michael Jordan never did. He never rested. He played every game. LeBron has the position to do this now, because they need him. The league needs him, and that's why he's doing all this crazy s--- now." Dennis Rodman, comparing LeBron James to Michael Jordan

James defended the value of resting players when asked last month about an issue that has been debated all season.

"It's a long, strenuous season and the NBA does a great job of putting the schedule together as best as they can," James said. "You're going to have back-to-backs. You're going to have certain games where certain things fall on certain nights, but a coach's job is to figure out a way for their team to compete for a championship, not compete for a game."

James also said he doesn't view rest as an issue that negatively affects the NBA.

Golden State Warriors coach Steve Kerr weighed in on Rodman's comments, jabbing the legendary rebounder for his history of on- and off-court issues.

"I saw Dennis Rodman was complaining about it," Kerr told reporters Wednesday. "I got a kick out of that because Dennis was suspended for 15 games a year, anyway. The guy got plenty of rest. Or [went to] Vegas or WrestleMania.

"He just took a night off whenever he wanted, so he can't complain."

Former Bull Charles Oakley also weighed in on his Twitter account, referencing the time Rodman once wore a wedding dress to a book signing.

In other comments, Rodman told CBS Sports that younger players can't handle the pressure that Knicks president Phil Jackson imposes on them and said that Carmelo Anthony will never win in New York.

"The people's mind-age now can't handle Phil Jackson, or people like him, mentally, man," Rodman said. "Phil Jackson lets you be a man first; that's the first thing he lets you do. And people like [Carmelo] Anthony and all you guys, stuff like that, that's called pressure, man. That's pressure. Especially in New York. ... Even though he's a great athlete, great player, [Anthony will] never win in New York."
