Caldwell changing special-teams coach

Posted by ESPN.com's Paul Kuharsky
Jim Caldwell has made his first coaching staff adjustment. The Colts just announced that special-teams coach Russ Purnell did not get his contract renewed.

Indianapolis' special teams have long been an issue, and the team has said its salary structure is a big reason. A star-laden team such as the Colts relies on a lot of youth and has few veteran backups, and those veterams are usually the core of special-teams units.

The Colts were the league's worst punt return team and ranked 28th in kick returns, while they were 15th in punt coverage and 24th in kick return coverage in 2008.

Purnell was with the Colts for seven seasons. He's also worked for the Seahawks, Oilers and Ravens, winning a Super Bowl ring with Baltimore.
