Carroll up to the challenge in NFL return?

The readjustment back to the NFL has led Seattle Seahawks coach Pete Carroll to occasionally reassess his approach.

Carroll, accustomed to winning big with regularity at USC, went into the season knowing two-minute situations would require more attention. He admitted this season to getting a little too casual with his game management when calling for an ill-fated quarterback sneak before halftime against San Diego. A week later, Carroll used two replay challenges in the first half of a 20-3 defeat to the St. Louis Rams.

So far this season, Carroll has appeared more aggressive than other NFL coaches in challenging disputed calls. Seattle leads the NFL in coach-initiated replay challenges with 13 after ranking tied for 20th with 12 total challenges over the previous two seasons. Carroll has won 46.2 percent of his challenges, which ranks 13th and stands just above the league average (43.6 percent).

The chart, based on data from ESPN Stats & Information, ranks NFL teams by most coach-initiated replay challenges this season. The Seahawks were the only team last season without a reversal. Former coach Jim Mora went 0-for-7 on challenges. Mike Holmgren won one of five in 2008 after winning four of five the previous season.
