So once the Heat dominated the Brooklyn Nets 105-85 on Wednesday night, James directly ripped Evans after the game.
Earlier Wednesday, Evans dismissed the Heat's championship-winning season.
"It doesn't prove nothing," the Nets' starting power forward told the New York Daily News. "That was a lockout season."
When James learned of the comments during the day, he tweeted: "Just keep throwing rocks at the throne, don't matter cause nothing can break my zone."
James had 24 points, nine rebounds and seven assists in the victory over the Nets, the third time Miami has blown out Brooklyn this season. Then he took aim at Evans' comments.
"You can't just come out and say something like that versus a champion," James said. "No one knows what it takes unless you've done it. You can't sit here and judge and talk about a team winning a championship unless you've done it. (Evans) hasn't done it."
James then looked down at the postgame stat sheet.
"Let me look at his numbers real quick -- he had no offensive rebounds, so we did our number on him," James said.
Evans had six defensive rebounds and two steals, but did not score in 20 minutes. James said he did not speak to Evans during the game.
"For what? I let my game do the talking," James said. "I'm not going to sit here and give Reggie Evans a lot of press, because that is what is going to happen for the next couple days."
Evans declined to speak to reporters after the game. But his teammates were not pleased with the team's effort this season against the Heat, who won the three games in the season series with the Nets by a combined 63 points.
"They're the defending champions, but I don't think they're much better than us," Nets forward Gerald Wallace said. "I don't think they're 20 points better than us.
"I'm not saying they can't beat us, but they're not 20 points better. ... They've embarrassed us three times. What does that say for us as a team trying to be a championship team?"
James said earlier Wednesday that he isn't too impressed by the Nets despite their recent turnaround under interim coach P.J. Carlesimo.
"(The Nets) just picked up the intensity level," James said. "You can tell that they like to play for P.J. ... It sucks that Avery (Johnson) had to take the hit of them not wanting to play at a high level."
Johnson went 14-14 this season as Nets coach before being fired in late December. Wednesday's loss dropped the Nets to 13-5 under Carlesimo.
"Our team is defending the Miami Heat. If our team has to defend one person, LeBron isn't going to score nothing. LeBron is no different from Joe Johnson or Andray Blatche. No different," Evans told the Daily News. "People need help (on defense). Some people don't need help. Everybody has to be double-teamed, it doesn't matter who you are. You just have to stop LeBron in transition.
"He's quick in transition. If you look at Joe Johnson -- Joe Johnson has two or three people trying to stop him. Whoever is guarding him."
James' team had a 6-10 record in his first 16 games against the Nets' franchise but has gone 17-0 since. He has scored at least 20 points in his last 20 games against the Nets, according to ESPN Stats & Information.
The sudden war of words between the two teams even ascended to the front office, with Nets general manager Billy King and Heat owner Micky Arison exchanging barbs on Twitter.
"Heading to the Barclays Center (King) we need to have a chat with Reggie Evans," Arison tweeted to King.
King responded by tweeting at Arison, "Looking forward to seeing you."
