Giannis Antetokounmpo nonchalantly acknowledged the Mavericks fans raining down "Fire Nico" chants, a trend that has followed since general manager Nico Harrison traded Luka Doncic. On Monday, as rumors regarding Harrison's imminent dismissal came to the spotlight, the American Airlines Center echoed the message as P.J. Washington prepared to take a free throw.Antetokounmpo's initial reaction on the court was him seemingly smirking, looking at the Jumbotron. Here's the clip:However, after the game, the two-time MVP claimed he couldn't hear what the fans chanted. Here's what Antetokounmpo told a reporter who asked if he had ever seen a fan base demanding a general manager's dismissal on such a scale:"That's what they were saying? I couldn't understand what they were saying."He added:"No. No, I don't think so, this is my first time (hearing it)."Before the game, ESPN's Tim MacMahon reported that it's a matter of "when, not if" that Nico Harrison will be fired midseason.The Mavericks' rough start with three wins in the first 10 (now 11) games with their new core, led by Anthony Davis and Cooper Flagg, has fueled the ownership's change of stance on moving on from Harrison.A well-conditioned Luka Doncic is averaging a league-best 37.1 points per game with 9.4 rebounds and 9.1 assists, making Harrison's controversial decision to trade him look even worse.According to Marc Stein's report from Sunday, the negativity surrounding the team has troubled and worn down the owners. Dallas' eighth loss on Monday, with Nico Harrison and Governor Patrick Dumont in attendance, reignited Mavericks fans' months-long protest.Mavericks governor Patrick Dumont takes matters into his own hands amid waning trust in Nico HarrisonMavericks owner and governor Patrick Dumont is taking matters into his own hands amid his waning trust in Nico Harrison's leadership. According to ESPN's Tim MacMahon, Dumont stepped in on Friday to stop the injured Anthony Davis from playing against the Wizards and avoid a long-term injury.Davis had missed five games until that point due to a left calf strain. Here's what MacMahon reported:"Dumont is now personally approving when AD can return from his calf strain, regardless of Nico’s opinion. AD wanted to play in Washington Saturday and there was “internal disagreement” over whether he should."Davis also wanted to suit up on Monday. Dumont and Harrison discussed it among themselves, while the team doctors and training staff were split. Here's what Mavericks reporter Brad Townsend wrote on X before the game:Brad Townsend @townbradLINKLike everyone, will be interested to see if Anthony Davis plays tonight. Told there was split opinion about him playing at Washington. Patrick Dumont and Nico Harrison discussed it. Davis wanted to play. Team doctors and the training staff were split. Decision was made to be prudent and wait.Nico Harrison coveted Anthony Davis, leading to Luka Doncic's trade. However, Davis has been a shadow of his past self with the Mavericks. Despite having a healthy last couple of seasons with the Lakers, he's played only 14 times for Dallas out of 46.It's been another massive reason behind the rejuvenated outrage against the front office executive.
