 An NBA Finals rematch in name only takes place this afternoon in Las Vegas. The Boston Celtics and Dallas Mavericks tip off from the pavilion. As the NBA Summer League continues, the Celtics have improved its exhibition record to 2-1 in the NBA Summer League. And the New England Revolution are back on the field tomorrow night. The club kicks off against FC Dallas at Gillette, New England Stadium. Gillette, Foxborough, I should say. New England has lost three straight and is last in the East with 22 points.
