Searching far and wide (left) for a FG miss

Two weeks ago, the Seattle Seahawks watched the Miami Dolphins kick the winning 43-yard field goal against them as time expired.

This past week, the Seahawks watched the Chicago Bears force overtime against them with a 46-yarder as the fourth-quarter clock ran out.

2012 Highest Opponent FG Percentage

Back in Week 4, the Seahawks suffered a 19-13 defeat at St. Louis when Rams kicker Greg Zuerlein connected from 24, 48, 58 and 60 yards.

Zuerlein did not miss against Seattle, but that by itself doesn't qualify him for special commendation. The Seahawks' opponents have made all 18 field-goal tries, making Seattle the only team in the NFL yet to benefit from an opponent's miss through Week 13.

The chart shows the five teams with the highest percentages of made field goals by opponents. Opponents for Arizona, San Francisco and St. Louis rank among the bottom seven in field-goal percentage. Blocked tries factor into the equation. Every NFC West team but Seattle has blocked one field-goal try this season. Sometimes, though, a team just needs its opponent to shank one.

The Cardinals' and Rams' opponents have each made 19 of 26 tries, tied for the second-lowest opponents' percentage (Tampa Bay, 68.2). The 49ers' opponents have made 16 of 21 attempts (76.2 percent).

Arizona led the NFL with five blocks last season. Seattle tied for second with three. The Cardinals' opponents had the third-lowest percentage made (72.9), while the Seahawks' opponents were fourth-worst at 75.7.
