Mavericks' Luka Doncic-Kyrie Irving combo gets GOAT proclamation from Jamal Crawford

Luka Doncic and Kyrie Irving are two players that are on opposite ends of their careers, yet are each two of the greatest guards to ever grace the court. The two of them joining forces on the Dallas Mavericks has been predictably lethal, so much so that former NBA players are now anointing them as the most skilled backcourt duo ever. Specifically, retired guard Jamal Crawford made the aforementioned claim on Tuesday on TNT's Inside the NBA. The three-time Sixth Man of the Year's opinion shouldn't be taken lightly, as he saw many quality backcourt duos over his 20-year career.
