Harrison Smith, just like anyone approaching middle age, has learned to accept the realities of getting older. The joints, for one, don't quite move as effortlessly as they once did.

Talanoa Hufanga will face the 49ers this week, and he joked that he's going to start a fight with Trent Williams.

Smith is one of 30 NFL players on training camp rosters who were born in the '80s. The fact that he is still playing at a high level is no accident.
