"We've got numbers on the defensive line right now," Harbaugh said. "We had a couple good pickups it looks like. Both of those two guys, Bilukidi and Guy, played well. They kind of fit our system really well. They're physical guys, they play hard and use their hands, they get off blocks. And with [defensive line coach] Clarence Brooks teaching them, they're only going to get better. That's very promising. I think we're going to be OK up front. I know we are."
