BEREA, Ohio – Browns coach Romeo Crennel isn’t satisfied that his defense has performed admirably against two of the league’s most experienced quarterbacks.

He’s also not going to allow his team to take one of the league’s newest quarterbacks lightly this Sunday.

Cleveland’s transition to a 3-4 defense hasn’t been the disaster that some predicted. But Crennel wants to see more than what he called the slow progress of the defense through three games.

The Browns held off Brett Favre long enough to pull out a win at Green Bay and limited Peyton Manning to one touchdown in a loss at Indianapolis.

After facing tough challenges against Manning, Favre and rising Cincinnati star Carson Palmer, the Browns get the chance Sunday to disrupt a quarterback with a lot less experience – Chicago rookie Kyle Orton.

However, Crennel, who earned three of his five Super Bowl rings as New England’s defensive coordinator, is more concerned about his defense executing properly than trying to disguise coverages and confuse Orton.

“We’re near the bottom of the NFL defensively,” Crennel said. “I’m not worried about him. I’m worried about us. You can’t take anyone lightly at the bottom. This is an NFL quarterback and he’s on the field. He’s got enough ability to be an NFL quarterback so you better honor him.”

The Browns have had a tough time getting to the quarterback this season. They have only three sacks and 11 pressures through three games.

Part of the reason Cleveland has had few sacks is because they rarely blitz. Cornerback Daylon McCutcheon said that’s part of their scheme.

“People get frustrated but the whole thing about this defense is to not give up big plays and keep the plays in front of us,” he said. “That’s the same thing they did in New England. That’s the same thing we did against the Colts.”

But Crennel has said he’d like improvement in the pass rush, which is something they worked on during their bye week.

Orton has a solid line in front of him and has been sacked five times in three games. But he’s thrown six interceptions, including five in a loss to the Bengals.
