Former Mavs PF/C Roy Tarpley, banned from the NBA for drug policy violations in 1991, then permanently barred in 1995 after his reinstatement a year earlier, passed away Friday in Arlington, TX. Plagued thru most of his stateside pro career with addiction issues, the NBA’s Sixth Man Of The Year in the 1987-88 season settled out of court with the NBA and the Mavericks in 2009 after suing the league for violating his rights under the Americans With Disabilities Act.
