"It depends on hang time," Harbaugh said. "We don't really have a depth issue. The whole dynamic of the kickoff return rules have changed. What happened is when you bring them out that deep, the geometry of the play has a changed a little bit, so you see more big plays."

Pees' schemes draw praise

Ravens' defensive coordinator Dean Pees' creative tendencies drew praise from his players, and Harbaugh.

With Pro Bowl defensive tackle Haloti Ngata sidelined Sunday with right knee and right shoulder injuries, Pees broke out a "dollar package," that had two defensive lineman, three linebackers and six defensive backs Sunday.

Pees deployed 6-foot-2, 270-pound rookie outside linebacker Courtney Upshaw at defensive tackle to take advantage of his quickness.

"They've been very creative," Harbaugh said. "They’ve done a really good job of mixing some fronts up and putting some guys in different spots to account for some of our personnel issues."

While generating three sacks and one interception, the Ravens also allowed 422 yards of total offense.

"Obviously, we didn’t have the yardage result we probably wanted.," Harbaugh said. "We’re a little disappointed with some of the yardage things. We didn’t want to give up those yards, and it was really five plays that accounted for most of their yards."

Progress for Upshaw

A second-round draft pick from Alabama, Upshaw finished the game with four tackles, one for a loss and one pass deflection.

For the season, Upshaw now has 36 tackles and one fumble recovery.

"Here’s our top pick, and he’s played a number of different positions," Harbaugh said. "Obviously, he’s been getting better every single week. He’s a smart football player. He’s a physical football player. He’s kind of the guy you look to."

More fake field goals?

In the wake of punter Sam Koch's touchdown run off a fake field goal against the Raiders, Harbaugh indicated this might just be a preview of more trickery to follow.

"There's always a chess match that way, season-long," he said. "It's good for people to know that we've got the ability to run that, but that's not a play that you only run once."

Koch scored on a two-point conversion run against the Steelers last season on a fake extra point.

"It's not a one-time type of thing," Harbaugh said. There were 29 minutes left in that game, and they gave us the same kind of look, and we ran it in there and got the extra point. It's really no different thinking than it was that game."

End zone

Harbaugh reiterated that the Ravens didn't suffer any major injuries Sunday, adding that Ngata and cornerback Jimmy Smith (groin) should be healthier after not playing this last game. ... Starting his first NFL game in place of Ngata, rookie seventh-round draft pick DeAngelo Tyson deflected two passes and had a quarterback hit.  "He played very well," Harbaugh said.
