NFL special teams units are vital to any franchise's season-to-season success. The San Diego Chargers were so poor in the third phase last season that even the league's No. 1 ranked offense and No. 1 ranked defense couldn't get them to the playoffs.
For years, the Bears generated points almost solely through Devin Hester returns. The Chiefs relied heavily on Dante Hall.
So it makes sense that teams would want some of their most talented players lined up deep to return kicks and punts.
But just because these five guys have the natural ability to make defenders miss and hand the offense good field position doesn't mean their health and availability elsewhere should be risked.
