Eagles defensive coordinator Billy Davis believes in 3-4 despite Philadelphia's struggles

Billy Davis isn't sugarcoating the way Peyton Manning picked apart his defense.

"We took a whooping," the Philadelphia Eagles defensive coordinator said Tuesday. "That's what happened. We did not play good enough to win, obviously. Those games are tough to swallow. But you move on from them."

Manning and the Denver Broncos dismantled the Eagles in a 53-20 victory on Sunday. No surprise, Manning did it to three other teams already this season and numerous times throughout his stellar career.

Before Manning, though, Philip Rivers, Alex Smith and Robert Griffin III, to some extent, each had their way with Davis' beleaguered unit. The Eagles (1-3) have the NFL's worst-ranked defense in total yards (1,787) and are second-worst in points (138).

Philadelphia — and Davis' 3-4 defense — meets the New York Giants (0-4) on Sunday.
