There’s no specific news hook for this post, other than we were talking about it among the TrueHoop Network, and it’s interesting.
Here’s a chart of the NBA’s average age season-by-season.
Seasons are denoted by their second year. For example, the 2010-11 season is shown on the graph as 2011.

It’s interesting how the gap between the weighted average age and the average age has closed.
Here’s a chart that includes the age of the oldest and youngest player each season.
