Maybe we should hold off on those plans for a championship parade next June. The Knicks are no doubt a legitimate threat in the Eastern Conference, as demonstrated by their encouraging 6-0 start. But like every other team they have issues, several of which were exposed in consecutive losses to the Dallas Mavericks without Dirk Nowitzki and the Houston Rockets with Jeremy Lin. Mike Woodson's club, which returns to the Garden on Sunday for a matinee against the Detroit Pistons, cautioned the media and fans not to overreact to a two-game losing streak, but even Tyson Chandler admitted being "concerned" over how the Knicks performed in Texas. Over the last six quarters, the Knicks have allowed 196 points, including 72 in the first half in their 131-103 loss to the Rockets on Friday. They were a step slow on the perimeter and were dominated on the glass while Chandler, the reigning Defensive Player of the Year, failed to provide any cover under the basket.
