The all-out effort certainly helped on the interceptions by linebacker Derrick Rodgers and Jamar Fletcher, who both caught passes that first went off Colts receivers.
"When you see that many guys around the football, there's definitely a lot of great effort out there," Wannstedt said. "But we can get a lot better."
The success of James on the ground was a price the Dolphins were willing to pay if it meant avoiding big plays by the Colts offense, something they partly succeeding in doing.
The Colts' longest play of the day was a 33-yard completion from Peyton Manning to Marvin Harrison that came just before the Dolphins' goal-line stand.
The next-longest play was a 26-yard completion to Troy Walters in the final minute that gave the Colts a chance to go for the end zone on the final play of the game.
But all in all, Wannstedt was pleased with the work of the defense. He made it a point to ask reporters to look throughout the season at how many points the Colts are scoring at home, saying, "They won't score 13 or less very often."
Wannstedt may have a point. The last time the Colts were held to 13 points or less at the RCA Dome was in November of 1999 in a 13-6 victory over the Jets.
