Yesterday, I wrote that NFL rookies were screwed by the CBA negotiated in 2011. Today, some more data on that point.
Using the Approximate Value metric created by PFR, we can calculate what percentage of league-wide AV belongs to each class of players. For example, rookies typically provide just over 10% of all AV in any given season; before the new CBA, that number was just under 10%. And when you combine rookies with 2nd, 3rd, and 4th year players, those players are responsible for just about half of all NFL value. Given that some 5th year players are also on their rookie contracts, it’s safe to say that about half (if not more) of all AV is provided by players on their rookie contracts.
The graph below shows, in a blue line, the percent of AV provided by players in their first four seasons. The orange line shows the percent of league-wide AV provided by rookies.
We don’t see an enormous switch post-2011 from vetearns to rookies, just a slight one. Players in their first three seasons produced 33% of all AV from 2006-2010, which jumped to 36% over the last five years. But the bigger point is just that football is, and has always been, a young man’s game.
