Colin Kaepernick strolled through the 49ers' locker room with about a dozen or so reporters, then made his way into a small nook where several offensive linemen sat in front of their stalls.

After some lighthearted protests and ribbing from his teammates left the 25-year-old quarterback chuckling quietly, Kaepernick turned stone-faced serious when questioned about San Francisco's passing game.

A season-opening win against Green Bay in which he threw for more than 400 yards and three touchdowns was supposed to have raised the bar for Kaepernick.

Instead it's turned out to be the high-water mark, and the 36th overall pick in 2011 has had a difficult time getting back to that point.

The 49ers entered the week 31st in total passing while Kaepernick had the fifth-lowest completion percentage among all starting quarterbacks.
