NBA World Stunned As Mavericks Fire GM Nico Harrison Months After Luka Trade

After months and months of pleading with team ownership to fire Nico Harrison, the general manager who helped orchestrate the bombshell trade that sent Luka Dončić to the Lakers, Mavericks fans were vindicated on Tuesday when news broke that Harrison is, in fact, on his way out.

Indeed, the Mavs and team owner Patrick Dumont have confirmed that Harrison has been relieved of his GM duties, effective immediately, and that Michael Finley and Matt Riccardi will serve as co-interim general managers in his place. The bombshell decision arrives just under a year out from said Dončić trade, and less than 24 hours after "Fire Nico" chants again broke out at the American Airlines Center during the Mavs' Monday night loss to the Bucks.

Considering the magnitude of the news, fans were extremely quick to react online ... and we're sure you can guess the tenor of the conversation. Take a look at that below:

One of the all-time sports villains. It just so happened his enemies were the fans of his own team. Turns out that’s not sustainable.

It remains incredible someone so incompetent was given so much power. Now he’s had it (rightfully) taken just months later. https://t.co/x7jRTLqV8M

There's just no way the Mavericks could keep going forward with the status quo. It's unfortunate because Harrison made some really, really smart moves until he made the worst trade in NBA history.

Firing Nico Harrison makes sense for the Mavs. You can't undo what's been done, but a fresh start is necessary. Crucially, a fresh start without any attachment to the players who are currently on the roster, minus Cooper Flagg who should be untouchable. Anyone else? Have a convo.

Nico Harrison eats free everyday in LA if you ask me.

Nico Harrison finding out he was fired on Twitter before walking into his meeting is poetic justice

They should have fired him the moment he walked in and proposed trading Luka. https://t.co/JbQ4uZXyVS

To allow the GM to trade away Doncic and then fire him less than a year later has got to be one of the legendary failures of organizational leadership in sports history. #Mavs https://t.co/xpHF4XPRRx

As a few experts and fans, like writer Zach Lowe, pointed out, however, Dumont did have a role in the trade at the center of all of this, too. Unfortunately for Harrison, though, Dumont is the guy who makes the decisions—which means Nico is just going to have to be the sacrificial lamb.

Is Patrick Dumont going to share responsibility for the Luka trade and try (again) to explain his role in green-lighting it and *why* he green-lit it?
