Via Keith Langlois at pistons.com: Drew (Detroit): I noticed on Friday a number of teams wore retro uniforms. I was wondering how teams get permission to wear the throwbacks and when was the last time the Pistons wore a uniform besides the traditional home and away? Langlois: Teams must submit uniform designs to NBA headquarters for approval and the process requires the submissions be made well in advance of use. The Pistons are submitting an alternate uniform to the NBA for approval for use in the 2013-14 season, Drew. The Pistons haven’t worn anything beyond home whites and road blues for the past three seasons. The last alternate the Pistons wore was the red uniform. H/T to Piston Powered.
