The Boston Celtics are one of many teams in the league with a decision to make on contract extensions ahead of the start of the 2017-18 season on Tuesday night.

According to Adam Himmelsbach of The Boston Globe, the Celtics could not reach an agreement on a new deal with fourth-year guard Marcus Smart.

The 23-year-old is set to enter the final year of his four-year, $14.8 million rookie deal that also includes a $6 million qualifying offer that would make him a restricted free agent next summer. Despite this latest development with his current contract situation, it doesn't necessarily mean that Boston doesn't want to keep him long-term.

It is likely that the Celtics are taking the “wait and see” approach to determine what kind of deal they want to offer Smart. This also allows for them to get a feel of what kind of market there will be for his services that will provide a clear indication of how much they value him.

Smart has developed into a dependable player on both ends of the court through his brief career in the league all spent with the Celtics. He is a stout individual defender that has become a reliable offensive contributor coming off his most productive campaign where he averaged a career-high 10.6 points along with 1.6 steals per game.
