NEW YORK—NBA officials are remaining quiet on the subject of the 2005-06 season's unusual opening week, in which seven games so far have opened with 0-0 ties. "I think that, despite what anyone may say about disappointing results, these games have proven that basketball can, in fact, be an exciting defense-oriented sport," Commissioner David Stern said during a press conference Thursday morning, after Wednesday's Milwaukee-New Jersey, New York-Boston, and Miami-Memphis contests ended with the score even at zero, exactly as in Tuesday's Milwaukee-Philadelphia and Dallas-Phoenix games. "I've talked to team owners and coaches, and while they're not happy with these final scores, the sudden increase in popularity among soccer-mad European and South American countries has made up for it somewhat." Stern had no comment on Tuesday's Denver-San Antonio game, in which the Nuggets shut out the defending champion Spurs 89-0.
