How did the Redskins suddenly become so good?

they've been this good all year, they've just been choking games away. they dominated green bay at lambeau field and lost on a 50 yard fumble return in the 4th quarter. they had buffalo beat before joe gibbs called those boneheaded back to back timeouts. they were beating the giants 17-3 at halftime in the first game and let them come back. they should have beaten dallas the first game except for jason campbells 4th quarter int. when they were driving for the winning touchdown. the skins could very easily be 13-3 or 14-2 right now.
