Dallas Mavericks general manager Nico Harrison said he “understands the magnitude” of the mega-trade he just pulled Sunday, sending Luka Dončić to the Los Angeles Lakers for Anthony Davis, but he defended the move by insisting it improved his team’s culture. “It’s important to know that (Dallas coach Jason) Kidd and I are aligned and we talk about archetypes and we talk about the culture we want to create,” Harrison said Sunday, seated next to Kidd before the Mavericks’ game in Cleveland. “There are levels to it, and there are people that fit the culture, and there are people that come in and add to the culture,” Harrison continued. “Those are two distinct things and I believe the people that are coming in are adding to the culture.”
