Matt Barnes Says JJ Redick ‘Doesn’t Give a S*** About Criticism,’ He’s A Good Coach!

Haters can save their breath when it comes to JJ Redick  … ’cause his former teammate, Matt Barnes, tells TMZ Sports the Lakers coach simply “doesn’t give a s***” about any outside noise.

Barnes played with Redick on the L.A. Clippers from 2013 to 2015 … and if there’s one takeaway he got from their time together, it’s that the dude stays focused on what matters — and definitely knows his stuff.

Now that Redick has landed his first head coaching gig (with the Purple and Gold, no less), all eyes are on him … and naturally, that puts his performance under the microscope.

But Barnes says none of that matters to Redick … ’cause ultimately, he’s a seasoned vet when it comes to blocking out the negativity.

“He doesn’t give a s*** about criticism,” Barnes said. “He played in the NBA long enough and been a star for long enough to let it go in one ear and out the other.”

Barnes continued to defend the 40-year-old coach … saying Redick is doing a good job of giving the Lakers an identity and empowering the players.

He also believes Redick will put in the work … and despite it being early in the season, he expects the Lakers to have a big year.
