CHARLOTTE, N.C. — Josh Hart said he has no time for “part-time” Stephen A. Smith.

“For me, Stephen A., as a part-time Knicks fan, needs to shut the hell up,” Hart said Thursday morning. “He barely knows guys that’s on the team.”

Hart was responding to recent comments from the ESPN personality made this week on his flagship show “First Take.”

“I need Josh Hart to be quiet,” Smith said. “Sit down. The only time I want you standing up and talking is when you’re playing.”

The context was Hart defending struggling teammate Mikal Bridges in an interview with The Post, which drew Smith’s ire as he lambasted Bridges’ play and the haul that team president Leon Rose gave up to acquire him.

“My God, that’s seven picks. Seven,” Smith said, referencing the draft capital the Knicks traded for Bridges in 2024, “for a dude that can’t even give you 10 points per game [over the last 10 games].”

Hart had told The Post that Bridges was catching “unfair flak” because his role was reduced and was simply “doing what’s been asked of him.”

“I’m definitely not going to listen to a part-time Knicks fan,” Hart added Thursday before the Knicks’ 114-103 loss to the Hornets. “When Stephen A. rolls up to MSG with a ‘New York’ on his chest and ties up his sneaks and plays for us, then I’ll listen to what he has to say.”

Smith often references his die-hard Knicks fandom on the air as a product of Hollis, Queens. However, as Hart alluded to, Smith’s knowledge of the Knicks has been called into question. In recent years, he botched the name of backup guard Miles McBride — calling him “Michael McBride” — he praised the contributions of Quentin Grimes, who had been already traded from the Knicks to the Pistons, and he dismissed Isaiah Hartenstein as “some guy” despite the center’s important role.

Hart and Smith worked together briefly at ESPN, for which the Knicks forward served as a guest analyst during the 2024 NBA Finals.

Since then, the Knicks made a series of all-in moves — including acquiring Bridges from the Nets — which, combined with firing Tom Thibodeau after a 2025 conference finals appearance, set the bar at NBA Finals-or-bust for this campaign.

At times, the Knicks, who carried a seven-game winning streak into Thursday night, have looked the part. At others, they’ve struggled — such as in their two ugly defeats this month in Los Angeles to the Clippers and Lakers.

Many of the early-season critiques targeted Karl-Anthony Towns. But, lately, the heat has shifted to Bridges, who entered Thursday on a 10-game stretch of averaging just 8.6 points on 37 percent shooting. It certainly set off Smith, who blamed Jalen Brunson for pushing the Knicks to trade for his former college teammate (although Smith later rescinded that claim).

Hart, like Brunson and Bridges, went to Villanova.

“Last year, [Bridges] didn’t have many plays called for him. This year, he probably has even less plays called for him,” Hart said. “So obviously there’s a mental hurdle he needs to get through, and that’s something where some of us can help him. I think he gets some of that unfair flak just because he’s doing what’s asked of him. And if we were to sit there and say, ‘Go shoot 15 shots a game,’ he would be efficient and he could do it. But that’s not what’s been asked of him.”

Smith vehemently disagreed with that take and told Hart to stand down. Hart clapped back Thursday.
