With the announcement of the reserves for the 2013 NBA All-Star Game, there are a handful of players who have been left out that come across as a bit surprising.
It's not that they were necessarily snubbed from the All-Star Game, but rather that they have been playing at such a high level for so long that it's surprising to not even hear their name mentioned.
There are players aging and regressing—that's for sure—but that might not be the main reason for the absence of some of the mainstays of the past.
In addition to plain old poor basketball, injuries have played a part. But the real reason for the change is that new players are maturing and becoming stars.
