Three games ago, the Philadelphia 76ers stood at 20-7 and looked like contenders in the Eastern Conference. Fast forward a week and the Sixers are 20-10 and sit in sixth place in the East. The three losses, to the Brooklyn Nets, Miami Heat and most recently, the Dallas Mavericks have given fans a cause for concern. However, no one knows the gravity of the situation more than 76ers head coach Brett Brown.

During the three-game slide, the 76ers have been outscored by an average of 14.3 points per game. To make matters worse, two of the three games (Miami and Dallas) were at home — where the Sixers were undefeated until this week.

Friday's loss to the Mavericks may be the most frustrating for the team. Without superstar Luka Doncic, the Mavericks were able to come into the Wells Fargo Center and do what they wanted. Philadelphia was outscored in the second half 54-41 and allowed Dallas to shoot 42.4 percent from deep.

Despite 33 points and 17 rebounds from Joel Embiid, the 76ers were unable to overcome the duo of Kristaps Porzingis and Tim Hardaway Jr. Porzingis would dominate in the post with 22 points, 18 rebounds and three blocks while Hardaway Jr. would hit seven of his 11 three-point attempts for 27 points.

The 76ers will next face off against the Washington Wizards in an effort to stop their three-game slide. The Wizards got the best of Philadelphia when the two teams last played on December 5.
