"What you try to do is balance all the players," Rosburg said. "You try to balance the starters' reps in various phases, you try to get your guys that aren't starters but that are playing a lot in sub-defenses perhaps or third-down packages for the offense, and you try to balance their reps, too. If there are guys not playing in any of that, then they need to do everything, and that's really the case. We've got some guys that are playing a lot on offense and a lot on defense, and we'll scale back a little bit of what their special-teams role is. That's going to be no different this week, and it's really been the same all year long. … We need guys out there that are going full speed. It's a full-speed game, and if you're playing a lot and then you have to go cover a kick, then it's not to your advantage to have someone that is fatigued out there. So we try to balance all the phases, and returners are going to be no different in that regard."
