1. The cornerbacks. Veterans Drayton Florence and Captain Munnerlyn have been getting most of the first-team work in camp. But second-year pros Josh Thomas and Josh Norman are still in the picture and could play their way into the lineup with good performances.
2. The playbook. I’m not expecting the Panthers to show every new wrinkle because they don’t want to reveal too much in the preseason. But I think we’ll get a gauge on if the Panthers are serious about getting away from Cam Newton running the read option and relying on a more conventional running game.
3. The backup receivers. The third receiver spot remains wide open. Armanti Edwards, Ted Ginn Jr. and Domenik Hixon all are in the mix. A good showing against the Bears could give one of them the edge.
