Grading the Lions

Lions coach Dan Campbell once again received a perfect grade on the annual report card from the NFL players' union.

Why it matters: The exercise helps monitor the league's working conditions and contributes to teams' reputations, which could come into play during future free agent negotiations.

Zoom in: Campbell, who's known for his inspirational words, got an A+ for the second consecutive year.

• The team's overall ranking out of 32 teams rose from 13th to ninth.
