A weekly look at what the Atlanta Falcons must fix:

As the Falcons prepare to face the league's top-ranked defense in the Detroit Lions Sunday in London, they know pressure will come at Matt Ryan from every direction.

Ryan was pressured on a season-high 32 percent of his dropbacks in this past Sunday's 29-7 loss to Baltimore, according to ESPN Stats & Information. It's no coincidence he was sacked a season-high five times. The pressure on his dropbacks has steadily climbed over the past five weeks (19 percent in Week 3, 23 percent in Week 4, 24 percent in Week 5, 29 percent in Week 6).

Surely the Lions picked up on the Falcons' inability to adjust to the variety of pressures the Ravens threw at them and how effective the Ravens were with stunts. The Lions ran some effective twists against Drew Brees and the Saints last week and also got after Brees with the blitz. And they got after Brees in the fourth quarter, putting him under duress on six of his 15 fourth-quarter dropbacks. Brees was 0-for-6 with an interception on those dropbacks.

Now against the Falcons, Ndamukong Suh and the Lions' front is sure to smell blood with a rookie set to start at center for the Falcons in James Stone. Suh and Nick Fairley will bring intense interior pressure, while team sack leader George Johnson and fast-rising Ezekiel Ansah -- the NFC's Defensive Player of the Week in Week 6 -- could give Falcons tackles Jake Matthews and Gabe Carimi fits on the edges.
