I thought that maybe Tomlin was playing with fire putting him out there with the recent knee injuries, and should have rested the knees. It's a long season, and he'd catch up a couple of games into the regular season. But Tomlin's playing hardball this pre-season, for better or worse.
That is not only stupid, but not related. Bell's injury to his knee had NOTHING to do with what happened with his foot. Totally unrelated. So resting him wouldn't have made one difference.
