Celtics Rumors: Avery Bradley, Marcus Smart, Jae Crowder on Trade Block

The Boston Celtics are "aggressively" shopping Marcus Smart, Avery Bradley and Jae Crowder in an attempt to carve out the cap space necessary to sign Gordon Hayward to his four-year, $128 million max contract, ESPN.com's Ramona Shelburne and Adrian Wojnarowski reported Wednesday.

Citing a source, the Norman Transcript's Fred Katz first reported Tuesday the Celtics were fielding calls for Smart. 

According to Shelburne and Wojnarowski, the Celtics have talked to "half a dozen teams" about different "trade concepts." 

However, the Celtics likely won't have much leverage since teams know they're hell-bent on clearing cap space to finalize a deal with Hayward.

Furthermore, parties interested in acquiring Smart, Bradley or Crowder know they can likely snag one of those three players on the cheap since the Celtics can't afford to take significant salaries back in a trade. 

As a result, teams with cap space that can absorb a contract without sending one back figure to be the most logical trade partners for the Celtics. 

Needless to say, all three wings would be valuable additions to teams in need of quality perimeter defenders. 

Smart is due $4.5 million this season and will become a restricted free agent next summer if he's extended a $6 million qualifying offer. 

Bradley, meanwhile, will earn $8.8 million in the final year of his contract.

Crowder is the best value of the bunch, though, at $6.8 million next season, $7.3 million for the 2018-19 campaign and $7.8 million in the final year of his deal (2019-2020).
