Eagles were impressed with Richard Sherman and the LOB

PHILADELPHIA -- After going head-to-head with Seattle Seahawks cornerback Richard Sherman and the Seahawks secondary, the Philadelphia Eagles say they now know the "Legion of Boom" deserves its reputation.

The Seahawks defeated the Eagles 24-14 Sunday, holding the explosive Philadelphia offense to only 139 total yards.

"Richard Sherman obviously is as advertised," said Eagles tight end Zach Ertz. "He’s a great player. [Seahawks cornerback Byron] Maxwell is no slouch either. Even though he doesn’t get the name recognition that Richard does, he is a great player, as well.

"I like to think I can get open regardless of how good a guy is, but they were better than us [Sunday] and eliminated some things."

Philadelphia had only 82 yards passing and quarterback Mark Sanchez completed only two throws more than five yards downfield.

"That’s a really good football team we played," Sanchez said. "They played really well in their zone and their man [coverage]. They took away a lot of opportunities. They put us in a lot of third-and-long situations that made it difficult. They have a sound system with great players in every spot.”

Philadelphia rookie receiver Jordan Matthews, who had only two receptions for 23 yards, was impressed with Seattle’s depth in the secondary.

"They have great players across the board," Matthews said. "They have guys that play in the slot that may be their third or fourth corner, but they are really good players."

On Sunday, the nickelback actually was Maxwell, one of the starting outside corners. But nickel cornerback Jeremy Lane was out with a glute injury, so Maxwell played inside most of the game while Tharold Simon, who had his first NFL interception, played outside. Backup cornerback Marcus Burley also had a sack Sunday off a blitz.

But it was Sherman who impressed Eagles coach Chip Kelly the most.

"I think Richard is the best corner in the league right now," Kelly said. "He’s proven it. I don’t think we did a good enough job from a protection standpoint for [Sanchez], but Richard played really, really well."
