The Panthers are frustrated that all-world defensive end Julius Peppers (right) has no sacks yet this year. Though he leads Carolina with 15 QB hurries, he's seeing more double-teams from running backs and tight ends, keeping him from finishing the job .... The Bills will have to sub battle-tested quarterback Kelly Holcomb for struggling starter J.P. Losman (48.1 completion percentage) if they're going to make a playoff run.... The Cardinals have allowed 96 points in three games while scoring only two TDs. "The whole thing is not working," says coach Dennis Green.... Brett Favre has seven picks in three games, and he's made his share of risky throws. But the Packers' unproductive ground attack ( Ahman Green has gone 10 straight games without rushing for 100 yards) is putting more pressure than ever on Favre to produce. "They've gotten away from handing [Green] the ball, which they'd been very successful at," says Tampa Bay corner back Ronde Barber. He's right: Green is averaging 15.7 carries a game, down from 22.2 in 2003.
