The modern NFL is less about keeping teams together and more about keeping as much of a team together as possible. Ask the Denver Broncos, who mostly made smart moves after winning Super Bowl 50.

Or talk to the Carolina Panthers, who bet on their team culture over one star player in Josh Norman and lost.
