Just hours after stepping foot in Dallas, Mavericks draft pick Luka Doncic is quickly endearing himself to D-FW sports fans.One of the best quotes from the Slovenian sensation's first news conference with the Mavs came when he was asked what he knows about his new home, the Lone Star State.Turns out not much, but just enough."I mean, I know about the Cowboys," Doncic said to laughter.Then he added that he knows that Texas will be plenty warmer than Slovenia, where it's "freezing all the time."We also learned that Doncic will wear No.
