The Indianapolis Colts hired Pagano as their new head coach on Wednesday, Jan. 25, 2012. The team said Pagano will be introduced at a news conference on Thursday.

INDIANAPOLIS — Chuck Pagano faces a big challenge in his first head coaching job.

He still can't wait to get started.

The Indianapolis Colts formally introduced Pagano on Thursday. The replacement for Jim Caldwell spent last season as Baltimore's defensive coordinator, and he is walking into a bundle of questions.

Fans want to know whether Indy will use the No. 1 draft pick on Stanford quarterback Andrew Luck, what the future holds for four-time league MVP Peyton Manning and whether the Colts are going to overhaul their defense.

Team owner Jim Irsay expects Pagano to improve Indy's defense and win more than two games in 2012.
