http://espn.go.com/blog/nfcwest/post/_/id/4447/three-of-nine-oldest-teams-in-nfc-west I bolded last years' playoff teams. I think this is a great sign, and with an outlook of continuity for once, I think it becomes even better. We are also the youngest team in the AFCE.
And under this staff I am sure it will continue to get younger with some of the older vets being replaced by younger players. Bodes well for the future with a young team that can grow together. Certainly better than having a team that finished 11-5 with a bunch of older players you know will have to be replaced soon.
