The week Philly had was an aberration. Carolina was a charity, as Singletary would say. But Philly is an aggressive D and typically gets points.
Would say it's a wash this week between Philly and Washington. Philly will give up more points, but get more TO's. Washington will keep the score down, and thus not as many opportunities to get TO's.
Myself, I'd roll the dice with Philly, since they have a better shot to score TDs off picks and Special Teams (but giving up alot of points could burn you).
