The Boston Celtics are playing well right now, but that is just one of the reasons they must keep their core around in 2013.
The Celtics' core has kept them a threat in the NBA for most of the past decade. They've endured injuries and role-player turnover and kept moving forward. They have proven time and time again that there is little that can stop them from achieving success.
Now they face their toughest task to date.
Rajon Rondo is lost for the season with an ACL injury, and Ray Allen now plays in Miami. That leaves Kevin Garnett, Paul Pierce and Doc Rivers as the only core Celtics members remaining at court level.
There are two other men who make up the core of the Boston Celtics franchise, though. Owner Wyc Grousbeck and general manager Danny Ainge are perhaps the most important members of the Celtics' core.
They will decide, for the most part, if the core stays together through 2013.
