Dallas Mavericks general manager Nico Harrison has come to rely on an old basketball chestnut as a catch-all explainer for why he made the now-infamous Luka Dončić trade. “Defense wins championships,” Harrison said Monday. “And we’re going to hang our hat on defense.” It’s a often-used expression around basketball. But is it right anymore?

Dallas Mavericks GM Nico Harrison has wasted an easy way for the team to be set up better for the future, and they're going to pay for it.

The Dallas Mavericks have a big decision on their hands this offseason. Nico Harrison is under as much pressure as any executive ever after trading Luka Doncic for Anthony Davis, with the entire city of Dallas calling for him to be fired.
