Indianapolis ? Jim Caldwell traded the perfect season for what he hoped would be the perfect ending.

Today, Caldwell and Indianapolis will play it by the book.

Nearly a month after the Colts coach pulled his starters against the New York Jets, granting Rex Ryan’s Christmas wish, the Colts can show everyone they made the right move by redeeming themselves in the AFC championship game.

“We’re very eager to get out there,” Colts defensive lineman Raheem Brock said. “We’ve got something to prove. They’ve got a good running game, a good offensive line, but now we’ve got to go out and prove ourselves again.”

In December, the Colts didn’t have to prove anything.

They were rolling along on an NFL record 23-game regular-season winning streak and had just set a franchise record with their 13th consecutive home victory. They had swept the AFC South, beaten seven straight teams fighting to make the playoffs, locked up the AFC’s top seed and had everyone talking about completing a 19-0 season.

Then Caldwell did the unthinkable. With less than six minutes to go in the third quarter, the Colts leading 15-10 and six quarters from being 16-0, he yanked Peyton Manning and the other starters to avoid risking injury.
