Dirk Nowitzki technically wasn't drafted by the Mavericks, who instead selected Michigan center Robert "Tractor" Traylor with the sixth overall pick in the 1998 NBA draft. Instead, the Mavs dealt Traylor to the Milwaukee Bucks for the rights to Nowitzki (ninth overall pick) and Pat Garrity (19th overall). Dallas then turned around and traded Garrity to Phoenix for Steve Nash. The rest is history.
