There are a few intriguing unrestricted free agents, all with different factors involving their futures with the Carolina Panthers.
There is no reason to believe the Panthers will apply the franchise tag. They might consider defensive tackle Star Lotulelei, but the defensive line is an area of strength with depth available behind him.
Guard Andrew Norwell might not be of high enough profile for the franchise tag, though he's steady and last season's glitches along the front are reason for at least moderate concern. It figures the Panthers will be serious about retaining him.
Then there's kicker Graham Gano, who had a career-best season after re-winning the job in training camp. It would be a stretch for the Panthers to tag Gano, though they probably don't want to take a step back if they don't keep him because he became so reliable. And still to be determined is the status of defensive end Julius Peppers and if he wants another season or opts for retirement.
