Al Horford: The veteran big man has been a key part of Boston’s dominant starting five but is still a drag on the team’s long-term plans from a financial standpoint with his partially guaranteed deal for next season ($14.5 million guaranteed of 26.5 million salary). The Celtics would still love to move off that deal for an expiring but league sources indicate that there are no playoff teams that have players they are willing to move for the 35-year-old Horford.
