The NFL's most accurate kicker failed the Colts in the clutch. By signing Adam Vinatieri, Indianapolis not only addressed that problem — it also took a key piece away from nemesis New England.

Indianapolis has agreed in principle to a deal with Vinatieri, the team announced on its Web site Tuesday. The Colts make the switch from Mike Vanderjagt — who misses the least — to the one who never misses when it matters most.

Vinatieri has hit two winning kicks in the Super Bowl for the Patriots. Vanderjagt's career accuracy rate is the best in the NFL, but twice in his career he missed critical field goals in the playoffs.
