Dennis Schroder: One of the hottest names on the trade market is far from a sure thing to be dealt as MassLive covered last month. The Celtics know he’s a flight risk but the possibility remains he could be retained in free agency since there’s unlikely to be many suitors that can offer much more than Boston, if they want to retain him. While several Eastern Conference teams have shown interest (Cleveland, Chicago, Milwaukee) in the point guard, it’s going to take more than a second-round pick and expiring contracts for Boston to move the point guard, per sources.
