Even Panthers have perfect score in first 4 matches, they will be more dangerous in the future because Luke Kuechly has cleared concussion protocol and is able to practice with his team again.
This score (4-0) worth even more when it is reached without one of the best linebacker in football.

Probably he will be in the roster for Panthers new match against Seahawks and try to beat bad result from the recent mutual history (0-4 in last three years).
