Dallas sports fans expressed their frustration outside American Airlines Center on Sunday after the Mavs' trade to the Los Angeles Lakers became official.

The is no precedent for what the Dallas Mavericks just did. Trading Luka Doncic feels like it will go down as one of the worst days in Mavericks basketball for Dallas fans, as the trajectory and future of this franchise has been forever changed with a nearly unbelievable deal.
