The Arizona Cardinals have allowed 48 sacks this season, most in the NFL, but they've allowed far fewer per game recently. Since giving up four sacks to the 49ers in Week 8, the Cardinals offensive line have given up nine sacks in four games. That is an average of 2.25 per game, far off the nearly five per game Arizona was allowing in the first eight weeks.

The Cardinals will need the offensive line to continue to improve against the Seahawks. Seattle's pass rush has sacked the quarterback 17 times in five games at CenturyLink Field, and their defense tends to play faster on the artificial turf. Quarterback John Skelton injured his ankle on a hit in the season-opener against Seattle, but was sacked just once.

Some of the offensive line improvement can likely be attributed to the play of rookie Nate Potter, according to arizonasports.com. He not-so-coincidentally has been at left tackle for the Cardinals each of the last three games.
