If the Lions are going to win the Super Bowl, they'll have to rely on far more than the group of stars that headline the roster.

Anzalone, Barnes and Campbell are back for another run. Rodriguez is on the shelf, but the Lions have some intriguing depth battles to watch for the next month-plus.

Maddox should feel pretty safe in his spot as the team enters training camp. He’ll surely be in the third safety role to open, but the Lions remain a merit-based team, so he’ll need to be looking over his shoulder at the youth behind him.
