NFL parity of all 32 teams has been the overarching objective of the League front office since the merger with the AFL. So, it's very difficult for a team to win every game in a season. It's rare to see a team manage to sweep their own division.
So, there will be losses. The focus going forward is to win the division. Sure, the playoffs are going to be tough, and, with the Packers in the playoffs, the road will probably go through Carolina. But, first things first. Win the division. Failing that, win a Wild Card slot.
It's a whole new season, as we all know, once the team is in the Playoffs.
My comments are close to being cliche, but, occasionally bear repeating.
