Jared Allen admitted before the Detroit game that he was a little frustrated because he wasn't getting many opportunities to rush one-on-one against left tackles.

Allen, who has posted 14-plus sacks for three consecutive seasons, said teams are using different strategies to neutralize his pass rush, including double teams, chip help from backs and tight ends and three-step drops by the quarterback.

In four games this season, Allen has been credited with one sack and no quarterback hurries. Defensive coordinator Leslie Frazier was asked about Allen's production Thursday and said "he’s playing well."

"What’s happening with Jared is that he’s still in a lot of situations where there are backs chipping and tight ends to his side and what it does is help other guys and helps our pass defense," Frazier said. "Our pass defense is really improved primarily because the type of blocks we’re getting from offenses right now. He’s going to have a bust-out game and hopefully it will be this weekend. He’s not a disappointment by any means whether it’s our run defense or pass defense. People pay a great deal of attention him. We just have to get the other guys who are getting one-on-ones to step up and help us in those areas."

Allen said he feels like he's getting close to the quarterback.

"That half-step, half-second is huge," he said. "There’s always what-ifs. But eventually they seem to come in spurts."
 
Allen had two sacks in the first three games last season and then collected 4.5 against Green Bay. He had three more sacks in the second meeting with the Packers.
 
"There’s always little things that you can improve on but you’ve just got to keep plugging away," Allen said. "Monday night I was there three times and could have had [Jets quarterback Mark Sanchez]. He escaped up the middle or I went this way, he went that way. It’s like a cat and mouse game. Eventually they’ll be sitting back there and they will come in bunches."
