Five nuggets of knowledge about Week 7:
Setting the tone with Beanie Wells: The violent stiff-arm Arizona's running back delivered against Minnesota demonstrated, again, what kind of runner Wells can be. The Cardinals should expect a strong effort from Wells against a Pittsburgh Steelers defense that has softened against the run. Arian Foster (155 yards), Ray Rice (107), Maurice Jones-Drew (96) and Joseph Addai (86) combined for 444 yards against the Steelers this season. Pittsburgh has allowed more yards rushing through six games this season (677) than it allowed through 10 games (630) last season. Wells is averaging 95.2 yards per game, fourth-most in the NFL. He ranks tied for second in rushing touchdowns with six despite missing one game to injury and having a bye week.
Solving Ben Roethlisberger: The Cardinals' pass defense has been a weakness. Conventional wisdom says defenses are best off keeping the Steelers' quarterback from setting up on the perimeter. So far this season, however, Roethlisberger has completed only five of 14 attempts for 57 yards with two touchdowns and two interceptions from outside the pocket. His Total QBR (7.0) and NFL passer rating (48.8) both rank 28th in the NFL from outside the pocket. Roethlisberger ranks among the top 10 in both categories from inside the pocket. He has been particularly effective on play-action passes (five touchdowns, one interception, 87.9 QBR, 117.7 NFL rating).
The Brandon Lloyd effect: Lloyd comes to the St. Louis Rams having suffering only one dropped pass this season, according to ESPN Stats & Information. The Rams "lead" the NFL with 15 drops. They are one of three teams -- Chicago and Week 7 opponent Dallas are the others -- to have more than seven players drop a pass this season (all three have eight). Lance Kendricks (four), Greg Salas (three), Danario Alexander (two) and the recently cut Mike Sims-Walker (two) have more than one drop for St. Louis. Whether or not quarterback Sam Bradford plays on a bum ankle, the Rams have to do a better job executing the basics, starting with holding onto the ball.
Seahawks' QB decisions in focus: Seattle faces Colt McCoy and Andy Dalton over the next two weeks after bypassing both young quarterbacks in recent drafts. McCoy went to Cleveland as a third-round pick in 2010; the Seahawks had no choice in the round that year after trading up to select receiver Deon Butler in 2009. Dalton went to Cincinnati with the 35th pick this year after Seattle used the 25th choice for tackle James Carpenter.
No time for Seahawks to relaxL: Seattle's road victory over the previously 3-1 New York Giants gave the team a 2-1 record over its last three games, casting the Seahawks as a young team on the rise. The Browns, meanwhile, have beaten only an 0-6 Indianapolis team and an 0-5 Miami team. Winning on the road was once a bonus for Seattle, but with San Francisco running out to a 5-1 start, including 3-0 away from home, the Seahawks need to beat bad teams on the road just to stay within striking distance. They are seeking victories in back-to-back road games for the first time since 2007.
