The AP reports: After 19 straight wins and an NBA record 27-2 start, the Boston Celtics have lost that swagger. The lockdown defense and the poise are missing, too, as teams line up to get a shot at the defending champions. On Tuesday, it was the lowly Charlotte Bobcats, as Raymond Felton scored 25 points and rookie D.J. Augustin added 11 of his 20 in overtime in a stunning 114-106 win that sent the Celtics to their fifth loss in seven games… Paul Pierce scored 28 points, but had a key turnover in overtime. Ray Allen scored 20 points, but shot 7-for-20. Rajon Rondo committed nine turnovers. Kevin Garnett had 14 points and 13 rebounds, but shot only 7-of-18 and was called for traveling in Charlotte’s decisive spurt… Bobcats F Adam Morrison had 13 points in his best game in a month.
