As the NBA offseason draws closer, rumors surrounding the Boston Celtics are starting to heat up. Brad Stevens is expected to make changes to the current roster, primarily due to the approximately $500 million payroll the team is facing for next season once luxury taxes are factored into the equation.

While the Celtics prefer not to trade one of their key core pieces, they're reportedly listening on almost everyone on the roster.
