However, another of Harrison's deals is also starting to look pretty bad and might not fly under the radar for much longer. Shortly after Doncic was traded, the Mavericks sent guard Quentin Grimes to the Philadelphia 76ers in exchange for veteran forward Caleb Martin.

Dallas Mavericks general manager Nico Harrison was welcomed by boos at the SMU-Pittsburgh basketball game on Tuesday.

Some fans in the Dallas area have been unhappy with Mavericks GM Nico Harrison since he shocked the sports world by trading Luka Doncic to the Lakers. Fans again voiced their displeasure during an SMU basketball game, chanting “fire Nico” at Harrison at Tuesday’s game against Pittsburgh at Moody Coliseum.

On Tuesday, somehow, Harrison and Dallas' nightmare continued. As SMU hosted Pittsburgh in ACC men's hoops action, the Mustangs' student section serenaded Harrison with chants of "Fire Nico"—while he was in attendance. Take a look at this video from Lia Assimakopoulos of The Dallas Morning News.

His track record as the GM of the Mavericks says Nico Harrison should be trusted, dealing Luka Doncic killed that.

Nico Harrison probably hasn't been very comfortable in Dallas since trading away Luka Doncic to the Los Angeles Lakers in the middle of the night, with no warning, for a package that included Anthony Davis and Max Christie.

For Harrison, winning just one title without Dončić won't do. He is all in, cards to the center of the table, certain he will prevail.
