As Ken Berger of CBSSports.com reported Friday, Rivers has a clause in his contract that prevents him from walking away from the Celtics and going to another team without compensation for the team. Thus, the reason Rivers is being included in these trade talks.
Rivers has three years and $21 million left on his current deal.
Garnett has a no-trade clause in his contract, but would be willing to waive it, according to the report.
The Celtics are looking to come to a conclusion on this quickly, and reportedly want a deal in the next day or two or they may walk away.
