Mark Cuban is FIRED UP for the Mavericks' hiring of Jason Kidd ... telling TMZ Sports he thinks the dude is "going to be great" for Dallas and its star point guard, Luka Doncic.
The Mavs owner spoke with us leaving Victory The Podcast in L.A. just hours after making the hire official ... and it ain't hard to tell, Cubes is expecting greatness from his team's new headman.
"I'm excited about it, obviously," the 62-year-old said. "J. Kidd is going to be great for us. He's going to be great for Luka, for the organization. I'm really excited."
You'll recall ... Kidd played for Cuban's Mavs from 2007 through 2012 -- helping the team win the NBA championship back in 2011.
And, when we asked Cuban if Kidd could repeat that feat as the team's head coach -- the owner said bluntly, "That's the whole idea, right?!"
"We've got the talent," Cuban added. "I think we'll get better talent. We'll keep on getting better. Luka will keep on getting better. And, I think Jason will help Luka and the team get better."
As for Luka's long-term future with Kidd ... Cuban said he has every intention of keeping his star in Dallas with Kidd for as long as he can.
"Obviously," Cuban said, "that's the goal."
