One could argue there’s a perception building that the role of free agency will be an afterthought in how teams build their defenses to get after the quarterback next season. But that perception might be wrong.

Niners QB Alex Smith injured his shoulder and left Sunday’s game after being driven into the turf by Panthers DE Charles Johnson.

The Cincinnati Bengals’ defense will be without its leading pass rusher, DE Antwan Odom, and nickel cornerback Adam Jones, both of whom were declared inactive for Sunday’s game against the Carolina Panthers.
