Even though the NBA world will always remember the Dallas Mavericks' 2025 trade deadline for their decision to trade Luka Doncic to the Los Angeles Lakers, they made another trade a few days later that had fans up in arms too. Dallas traded Quentin Grimes to the Philadelphia 76ers for Caleb Martin, and this move blew up in their face when Martin struggled in Dallas while Grimes thrived for the Sixers.
Now, with Grimes' high free agency demands in Philadelphia, this trade looks a little less bad for the Mavs. Still, they lost the best player in the trade in Grimes while also coughing up a valuable 2025 second-round pick (which turned into Johni Broome).
