It comes as no surprise considering the Heat are in need of a shooter from the outside to compliment LeBron James, Dwyane Wade and Chris Bosh. Despite an incredible Game 5 performance in the Finals, Mike Miller is a shell of his former self, leaving space for a sharpshooter on the Miami roster.
Boston might be ready to retool, considering the collective age of Allen, Paul Pierce and Kevin Garnett. While the Celtics fought admirably against the Heat and almost defeated them, the reality is a window that has probably closed on this group.
It doesn't make much financial or basketball sense for General Manager Danny Ainge to re-sign Allen at this point. While he served his purpose and helped restore glory for Boston, it's most likely in both parties best interest to move on.
