WASHINGTON (AP) -- The NFL is trying to spread ''Hard Knocks'' around.
At their fall meetings Tuesday, owners approved a measure that allows the league to choose which team will be the focus of the documentary-style show if no club volunteers.
Certain teams would be exempt from being forced to participate in the filming:
- those with new coaches;
- those that reached the playoffs in one of the previous two seasons;
- those that appeared on ''Hard Knocks'' within the preceding 10 years.
So far, only seven of the 32 NFL teams have been on the series, which airs on HBO: Dallas Cowboys (twice), Cincinnati Bengals (twice), New York Jets, Baltimore Ravens, Miami Dolphins, Jacksonville Jaguars, and Kansas City Chiefs.
