2013 AV-Adjusted Team Age

January 30, 2014 Statgeekery

In each of the last two years, I’ve presented the AV-adjusted age of each roster in the NFL. Measuring team age in the NFL is tricky. You don’t want to calculate the average age of a 53-man roster and call that the “team age” because the age of a team’s starters is much more relevant […]

The 2012 Colts were very rookie-heavy, with one big exception

July 22, 2013 Random Perspective On

Last week, I wrote about how the 2012 Redskins were powered by a pair of rookies in Robert Griffin III and Alfred Morris.

Last summer, I looked at the age curves for running backs in an attempt to find out if there is a magical cliff at age 30 (there isn’t). But when I wrote about Josh Freeman last week, I started thinking about quarterback age curves. The first step in trying to measure the aging patterns of […]

2011 Age-adjusted team rosters

August 1, 2012 Statistics

Measuring team age in the N.F.L. is tricky. Calculating the average age of a 53-man roster is misleading because the age of a team’s starters is much more relevant than the age of a team’s reserves. The average age of a team’s starting lineup isn’t perfect, either. The age of the quarterback and key offensive […]
