Marcus Smart could find himself out of Boston and into a new jersey sooner rather than later. 

The New York Knicks are amongst the handful of teams that have reportedly called the Celtics about Marcus Smart's availability, as he becomes a restricted free agent this summer and provides an intriguing set of skills. Smart may not be the most attractive option at guard for the New York Knicks based on his limited scoring ability, but his menacing defense and relentless energy are undeniable.

The Knicks aren't the only one vying for Smart, however, as they join the company of the Kings, Nuggets, and Pacers, per Yahoo Sports' Chris Mannix.

The 24-year-old guard actually had himself a decent 2017-18 regular season from an offensive standpoint, averaging 10.2 points and 4.8 assists per game, though he's consistently struggled with jumpers. Where Smart really shines is on the other end, however, as finished 6th in the NBA in defensive win shares. But with the emergence of Jayson Tatum and Terry Rozier, Smart has found himself often searching for minutes, starting just 11 regular season games.

It's worth noting that the Knicks are in desperate need of defensive help after they finished 23rd in the NBA with a defensive rating of 108.4 this past year.

If the Knicks were to acquire Smart, he'd immediately push Courtney Lee and Emmanuel Mudiay for playing time. Many of his contributions to a team are not so easily calculated, ​​yet he still holds a tremendous amount of value, especially at just 24 years old. Keep an eye on New York, as he could be too easy to pass up if the Celtics aren't aggressive about matching offer sheets.
