The first week of the 2012 NBA season is in the books, and we've seen a few teams and players unexpectedly struggling. Which team do you think is the biggest letdown thus far?

Boston remains one of the older teams in the league (besides the San Antonio Spurs and the New York Knicks, that is). The Celtics made some off-season moves for younger guys but are still relying heavily on their veteran players. Boston currently sits at 1-2.

Heading west, the conference-champion Oklahoma City Thunder traded young star James Harden, while still retaining plenty of highly gifted players, and are at 1-2 in a tough division with a lot of talent.

Even farther west are the Los Angeles Lakers. With the additions of Dwight Howard and Steve Nash, many thought they were championship-bound. They finally got a win last night to avoid an 0-3 start. That win, though, came against a very weak Detroit Pistons team.
