Celtics fans are slowly coming to grips with what it feels like to rebuild after a long, sustained run at the top. This rumor was started on Bill Simmons podcast. Simmons is connected, but he is primarily a Celtics fan. The reality of Boston basketball is that they are about 4 million over the luxury tax right now, not including the draft picks to come. Paul Pierce is going to make about 15 million if he is on the roster after June 30th, but they will probably cut him and pay the guaranteed 5 million. Pierce leads the Celtics in many career categories, so while that would be the financially responsible thing to do they don't want to do it.
So, Celtics fans are praying that they can trade Fall Fierce for some kind of asset, but more importantly, to save face. Cleveland knows that a rebuild is long and sometimes painful. Boston hasn't figured that out yet.
