The New York Giants remained in postseason contention with one of the most lopsided victories in their long rivalry against Washington, beating the Redskins 45-12 Monday night. Eli Manning completed 19 of 26 passes for 268 yards and three touchdowns, and Ahmad Bradshaw ran for two scores for the Giants, who have eight wins and six losses and are one game behind Dallas and Green Bay in the battle for wild-card spots with two weeks remaining in the regular season. A loss would have left New York with only the faintest of playoff hopes. The Giants marched downfield at will to take a 24-0 halftime lead. At one point in the second quarter, they held a 226 to minus-2 advantage in total yards, a 16-0 dominance in first downs, and the time of possession gap was roughly 21 minutes to 4½. The Redskins went three-and-out on their first three possessions, finally got a first down on the fourth, then tried to pull a ridiculous-looking fake field goal on the fifth – a play that produced a Giants interception to end the half. Even when the Redskins scored their first touchdown - with the game already out of reach in the third quarter - the Giants blocked the extra point. The Giants defense, with its habit of giving up big-yardage plays, had largely been the culprit as the team lost six of eight games to waste its five-match winning run at the start of the season. The unit was stout, however, against the Redskins - even with defensive backs Corey Webster and Aaron Ross inactive with injuries. Terrell Thomas got his fifth interception of the season and turned it into his first NFL touchdown with a 14-yard runback. Bradshaw had touchdown runs of 3 and 4 yards in the first half and was greeted both times with snowballs thrown from the stands. The Redskins had to remove tons of snow from the stadium and their parking lots just so the game could be played. Cowboys sign Suisham The Dallas Cowboys have signed kicker Shaun Suisham to replace the released Nick Folk, the team said Monday. Suisham had kicked 18-of-21 field goals for the Redskins this season but was axed by Washington after missing a 23-yarder that cost his side an upset win over the New Orleans Saints earlier this month.
