1 Will Charlie Whitehurst survive the game?

The Giants have a penchant for knocking out quarterbacks and Whitehurst would certainly be the least-famous of the victims. The fifth-year veteran, who replaces Matt Hasselbeck (concussion), has never thrown a regular season pass.

New York leads the NFC in sacks (24) and fumble recoveries (9) and also has seven interceptions. Now is not the time to get your feet wet — especially with reigning Defensive Player of the Month Osi Umenyiora rushing from Whitehurst’s blindside.

2 Can the Giants protect the football?

Eli Manning and Co. lead the league in turnovers (22) and have a habit of putting the ball into the opponents’ hands – whether it’s by fumble, tipped passes or errant throws.

It could be more of the same Sunday as the forecast calls for slight precipitation. Throw in the fact Seattle owns a plus-eight turnover edge at home and it could get ugly for Big Blue.

3 Who has the better return game?

Seattle is 3-0 at home, mostly on the backs of its return units. Specialist Leon Washington is back to putting up the ridiculous numbers (33.7-yard kickoff return average) he had with the Jets before a gruesome leg injury, and rookie Golden Tate has been equally effective, gaining 11.5 yards per punt return.

“I have a lot of pride in what I do,”?Washington said. “[The Giants] haven’t given up anything really, really dramatic [lately].”
