The Giants have spent part of the week trying to figure why they couldn't put any pressure on Saints quarterback Drew Brees in Sunday's 48-27 loss. And it's not like Cardinals quarterback Kurt Warner's been a sitting duck this season. Giants defensive end Justin Tuck told reporters this week that Warner is unloading the ball -- snap to release -- in 2.2 seconds, which is pretty impressive.

On Thursday, Pro Bowl defensive end Osi Umenyiora vowed to tweak his approach in order to put more heat on the quarterback. He thinks he's been a bit too conservative in his approach and plans to turn it loose against the Cardinals on Sunday.

"Sometimes when you get into that mind frame that you’re going to rush, you just have to rush,” Umenyiora told reporters Thursday. “You can’t be sitting over there taking what they give you. You have to dictate to them exactly what you’re going to do. I don’t want to be sitting there thinking it’s a run when it’s a pass. I just want to take off, which is what I’m definitely going to try to start doing a lot more of."

The Cardinals are a much more predictable team than the Saints in that they don't try to run the ball much. The Giants can't completely blow off the running game, but I think they can be a little more aggressive against the play-action game. It also helps that the Giants have good memories from their last game against the Cardinals.
