With a 10 game win streak on the line Monday night, the Celtics put up an underwhelming performance in Chicago against a hungry and desperate Bulls team. Boston was leaning heavily on their three point shooting, where they shot nearly 40% from on the night; however, the team's offense wasn't the reason why the Celtics lost, it was their defense.

Every time the Celtics needed a crucial stop, the team couldn't manage to put together a solid defensive possession, and it eventually led to their fourth loss of the season. Boston has now lost two games to Chicago, with one remaining game between the two teams yet to be played. But after a lackluster defensive performance where the team sleepwalked through most of the game, do the Celtics have some serious concerns about their defensive scheme?
