The Boston Celtics' loss to the San Antonio Spurs on Sunday marks the team's fourth straight defeat. Despite this, veterans Kyrie Irving and Marcus Smart remain optimistic.

After the game, Smart admitted that the team is still figuring out how where everyone on their roster excels. Nonetheless, he believes that once they find it, it's all going to flow from there.

Irving, for his part, tagged their slump as a challenge. However, He believes that at the end of it all is a great reward of lessons to be learned.

While they'll qualify for the playoffs this year, the way the Celtics have been performing has been a cause of concern all season long. They house one of the talented rosters in the entire league. Apart from Kyrie Irving and Marcus Smart, they also have All-Star caliber players in Al Horford and Gordon Hayward.

Not to mention they have young players in Jaylen Brown and Jayson Tatum who are brimming with potential. And they are led by Brad Stevens, whom many say is one of the best coaches in the NBA.

For some reason, the Celtics are not clicking this year, but they still have eight games regular season games remaining to solve all the issues houding them. After all, come playoff time, it's either win or go home.
