It’s been a disappointing season for Allen, because privately, he feels somewhat slighted by an organization for which he developed a loyalty and trust - and his demeanor has changed over the past few weeks.
In addition to being nearly traded, Allen was relegated to the bench by the emergence of Avery Bradley, a move that has made the Celtics more athletic and more effective defensively.
It appears that Allen would appreciate better communication from team management.
It seems while the Celtics have undergone a resurgence - primarily because trades for Allen and Pierce never materialized - there has been a breakdown in communication and perhaps regard between management and those veteran players.
The wedge may be too late to close. Allen wants to finish this season with a championship, but the likelihood of his return next season has diminished.
