Of Alex Smith’s 92 pass attempts, only four have traveled 20 yards or more downfield to a wide receiver.

Smith has also targeted Vernon Davis with three deep balls.

Ryan Fitzpatrick of the Buffalo Bills is the only other quarterback who has attempted fewer long balls than Smith.

The 49ers' new additions of Mario Manningham and Randy Moss was expected to stretch the field vertically.

“We’re still trying to get on the same page,” said Manningham, whose 9.4-yards-per-catch average is well below his career mark (14.1). “We’re not fully on the same page like we want to be – me and him, or him and the other wideouts. But I feel like we’re getting there.”
