The Celtics have a brutally difficult start to the season, especially for a team with so much change, and they were in real danger of digging themselves a nasty hole after they lost a winnable game against the 76ers in the opener. Losing to the Knicks and Pistons weren't problematic results in a vacuum, but with two three-games-in-four-nights stretches and contests against championship contenders on the horizon, the Celtics had a chance to go winless or 1-6 in their first seven games.
