LeBron James can say he didn’t have any extra motivation when he took the Madison Square Garden court Wednesday night, but he appeared to be looking right in Phil Jackson’s direction after a few of his baskets.

This was James’ first time facing the Knicks since Jackson referred to the Cavs’ superstar’s friends and business associates as a “posse.” James took umbrage with the term and then took it out on Jackson’s Knicks.

James scored 25 points in just three quarters of action. He wasn’t needed in the fourth since the Cavaliers were in control from the opening minutes of the game. The NBA champs led by 34 points and rolled to a humbling 126-94 victory over the previously surging Knicks.

“I’m motivated for the love of the game,” James said. “I’m motivated by the process. I’m motivated knowing that my kids are watching on national television. I don’t need much more.”

The Cavaliers (15-5) handed the Knicks their worst loss of the season, and snapped their four-game winning streak. The Knicks (12-10) had won 9 of 12 before Wednesday night. To add insult to insult, James and several Cavaliers were flipping water bottles on the bench in the fourth quarter.

“It’s definitely embarrassing to get blown out on national TV,” Brandon Jennings said. “I don’t care what the situation is, how many games we won in a row. Nobody wants to be embarrassed on national TV.”

The Knicks came into this game with the best record in the Eastern Conference since Nov. 13. But they looked worn out from playing the night before in Miami and had to face a team with a superstar driven to ruin Jackson’s night.

The Knicks also were without Derrick Rose because of lower back pain he started feeling in Tuesday’s win in Miami. They hope it’s a short-term injury.

An MRI on Rose’s back showed no structural damage. The Knicks say Rose is day-to-day. He’s expected to travel with them Thursday morning when the fly West for a five-game trip.

Jennings had 16 points and Courtney Lee 15. Kristaps Porzingis scored 12, and Carmelo Anthony took just eight shots and had a season-low nine points.

“We just want to put this game behind us,” Anthony said. “It was overall a bad night. I don’t want to get into specifics or anything like that. We’re just going to chalk this one up as a tough night, bad night and put this one behind us and get ready for this road trip.”

Leading up to this much-anticipated game, James said his approach wouldn’t be any different because of Jackson.

But James didn’t appreciate the Knicks president saying he likes to get special treatment in an interview last month with ESPN.com. And using the word “posse” set him off. James considers it a racially charged word.

“I’m not answering any Phil Jackson questions,” James said at the morning shootaround.

Jackson said he probably could have chosen a different word, but didn’t plan to clear the air with James, calling it “water under the bridge.” But James said he wouldn’t entertain a conversation with Jackson anyway.

James’ play did his talking.

“It was just a little bump in the road and a game we didn’t play our best,” Anthony said. “We want to put this one behind us but we also want to learn from this and get better and move forward.”
