For a football stadium BofA is pretty good. The layout is easy to get around- there's plenty of room to walk. Concessions are everywhere, and some are pretty good. Find a JJR's BBQ Shack- the pulled pork is pretty good and the BBQ nachos may be the best stadium nachos ever.
If you're in the upper levels, the stairs are steep. You can see the field from just about anywhere- even high up. Although with the Panthers playing, you'll probably have a better time enjoying the concessions and shopping. But if you do choose to watch, the seats are fairly comfortable. There's not a lot of leg room between rows of seats though, so climbing in and out of rows is a bit tricky.
This may not be the newest stadium out there, but it does the job. If you leave disappointed it won't be because of the stadium.
