The Boston Celtics are struggling. There is no denying the fact that they play differently from the way they did a season ago.

In the 2017-18 season, the Celtics won 55 games and only trailed the Toronto Raptors by four games in the Atlantic Division.

The case is different now. They have started the season 9-9 and have currently dropped their last three matchups, including a 117-109 loss to an awful New York Knicks team on Wednesday.

Celtics head coach Brad Stevens expressed his disappointment, per Chris Forsberg of NBC Sports Boston:

Coach Stevens stated that the problems the Celtics are facing right cannot be just attributed to a specific player or players, but to their entire team. He also said they'll evaluate their team's struggles piece by piece to be able in order to resolve their issues.

In their loss to the Knicks, the home crowd loudly booed their team after going down 16 points in the second quarter. Boston went on to allow an abysmal 65 points in the first two quarters alone, which is unlike them given their typically strong defense.

Though they have faced some roadblocks early this season, the Celtics still hold the eighth position in the weak Eastern Conference. Whatever troubles they are facing, Boston needs to adjust to be able for them to match the performance from previous seasons.
