Cracks in the foundation

The Celtics are built on stifling defense, and that hasn't been a hallmark of their play in recent games. Forget the phantom bucket against the Blazers (where a Travis Outlaw dunk was allowed despite the fact six Portland players were on the floor), the Celtics haven't been able to get stops when they need them (like during overtime against the Bobcats Tuesday). "Teams are going to make adjustments to how we are playing," said Kevin Garnett.
