Bowles, who replaced Juan Castro as Andy Reid's defensive coordinator, has had two weeks to get his defense ready for Atlanta. Still, even with the bye week, Atlanta doesn't expect to see much change defensively from Philadelphia.
"It's still going to be the same guys we've seen on film," McClure said. "I don't think they are going to drastically change what they've done. They've had training camp to put in their defensive philosophies and the first six games of the season. I just can't see them changing too much."
Under Castro in 2012, the Eagles allowed 20.8 points per game, and ranked in the middle of the pack in opponents' passing yards per game (222.6) and rushing yards per game (104.5).
Philadelphia's defensive scheme is likely going to be identical to what they've run through the first part of the season, but their aggression on defense may change under Bowles.
Bowles hasn't served as a defensive coordinator in the NFL until now, and he last served as a defensive coordinator in 1999, with Grambling St. Bowles had been serving as Philadelphia's defensive backs coach prior to the promotion.
