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.

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 Monday night the jumbotron showed fans as part of a karaoke bit, before one man took his chance to clearly mouth “FIRE NICO.” The camera quickly cut away, and within minutes security descended on the fan and escorted him out of the arena.
