Quit searching for a comparison for Dallas Mavericks wunderkind Luka Doncic. Because no NBA player has ever put up these type of numbers in his age-20 season. In the time it took for New York executives Steve Mills and Scott Perry to perhaps set up coach David Fizdale to take the fall, Doncic has kicked off his sophomore campaign by averaging 28.3 points, 10.3 rebounds and 9.1 assists over the first 11 games for the Mavericks (6-5).
