Nearly five years after his departure, Ray Allen's former Celtics teammates still have issues with the way he left Boston. Kevin Garnett invited four of his former teammates from the world champion 2008 Boston Celtics to join him Monday on his "Area 21" segment before TNT's broadcast of Game 4 between the Golden State Warriors and Utah Jazz: Paul Pierce, Rajon Rondo, Kendrick Perkins and Glen "Big Baby" Davis. Notably absent: the third member of the Celtics' vaunted Big Three, shooting guard Ray Allen.
