INDIANAPOLIS — New Indianapolis Colts coach Jim Caldwell says he wants to build on Tony Dungy's success, not be a carbon copy of his former boss.

The Colts introduced Caldwell as their coach Tuesday, a day after Dungy stepped down after seven seasons.

Caldwell's hiring was part of a succession plan the Colts announced last year when he was named associate head coach.

Caldwell has a four-year deal but team owner Jim Irsay would not disclose the financial details other than to say it was competitive for a first-time NFL head coach.

Caldwell's only previous head coaching experience came at Wake Forest, where he went 26-63 in eight seasons beginning in 1993.

Caldwell said he would put his own stamp on the team and that might include changes on the coaching staff.
