Former NBA veteran Kendrick Perkins didn't mince his words as he admitted that the current Boston Celtics team has underwhelmed as of late. With their ongoing slump, Perkins claimed that they may not even make it out of the first round amid the high expectations set around the team this season, via NBC Sports Boston.

Kendrick Perkins certainly knows a thing or two about the organization's winning culture as he previously played eight and a half seasons with the Celtics from 2003 to 2011, highlighted by a championship crown in the 2008 season. He claimed that there will always be high expectations for the Celtics every season, given the team's winning tradition.

Meanwhile, the Brad Stevens-led team is currently plummeting at a crucial stage in the season, only a couple of weeks away from reaching the halfway mark of their campaign. On Tuesday night, the team encountered another bump in the road as they absorbed a disappointing loss at the hands of the Dallas Mavericks.

After being named as All-Stars this season, both Jaylen Brown and Jayson Tatum stepped up for the Celtics by scoring 29 and 28 points, respectively. However, Mavericks guard Luka Doncic's successfully drained the last gasp game-winning three-pointer to run away with a 110-107 victory.

The three-point loss against the Mavericks extended the team's losing streak to two games. Boston dropped to a 15-16 record for the sixth spot in the Eastern Conference as the Celtics slid to below .500.

With a handful of promising players on their roster, it would be a disappointment to not see the Celtics make noise in the coming postseason. Head coach Brad Stevens and his team will definitely have to ramp up their efforts if they want to climb up the standings amid the tight competition in the Eastern Conference playoff race.
