This is what I like about the San Francisco 49ers' offseason moves: They were extremely aggressive in their efforts to get stronger on defense. They attacked the chore of finding new starters through free agency and the draft.

This is what concerns me: Smith no longer has Norv Turner, who left to become head coach of the San Diego Chargers, as his offensive coordinator. Turner had plenty to do with the significant strides that Smith made last season. It's possible that Smith might take a step or two backward before finding a new comfort zone.
As impressive as the 49ers were in addressing their defense, there still is at least one lingering concern on that side of the ball -- the line.
