If the Mavericks decide to move on from Harrison, a logical replacement option already exists within the organization’s basketball operations structure: assistant general manager Matt Riccardi. Riccardi has been a consistent presence within the Mavericks’ front office, frequently involved in day-to-day logistics, and regularly seen on the court pregame, interacting with players and executives. He has developed a strong rapport with players, most notably Kyrie Irving, with whom he has worked in Brooklyn and Dallas.

“Nico Harrison did not want to do this closed-door roundtable. This was not his idea. This was something that was enforced by their owner, Patrick Dumont.”

Was part of the group that interviewed Nico Harrison.
Asked if he maximized the return for Luka.
Nico: “We got what we wanted.”
Asked if Nico sees himself in Dallas long term.
Nico: “I have 3 years left on my contract. I see myself finishing it out.” nytimes.com/athletic/62814… – 4:00 PM

Shams Charania: Reporting for NBA Countdown on the target return for Dallas Mavericks All-Star Kyrie Irving after his March ACL tear: -via Twitter @ShamsCharania / April 16, 2025
“Would you say he was the guy that you probably had the most battles with? Or Kai? Or Steph?” Damian Lillard: “Definitely Russ. I would say Steph, because I’ve played more playoff series against Steph. And obviously, being in the West, we played each other all those times—even preseason. I’ve seen a lot of both of them. But I played Steph in more playoff series. As far as it being personal? It was more me against Russ. With Steph, it was always like—Steph took off, and I was chasing. I wanted what he had. He’s winning championships, everybody’s talking about him. So I was very competitive with Steph—especially in those years where I was like, ‘No, I can do that too.’” -via YouTube / April 12, 2025
What do you think happens with Kyrie Irving this summer, contractually? MARC STEIN: I mean, the injury obviously makes it more complicated. Without the injury, he had a massive amount of leverage —and I think he still has quite a bit —because, as you saw, L.A…. I mean, AD’s performance, we have to factor in the Lakers doubled him pretty strongly.” -via YouTube / April 11, 2025
