It was Auerbach who nixed Parker and insisted that North Carolina shooting guard Joe Forte be the team’s pick at No. 21, a fact confirmed in recent days by several league executives familiar with the Celtics decision on what would become a fateful night for the Spurs. Auerbach, one executive said, remained skeptical of European point guards. Plus, he had seen many of Forte’s games when Forte was a star for DeMatha Catholic High School, the famed hoops program in Hyattsville, Md., run by Auerbach’s friend, legendary prep coach Morgan Wootten.
