Andrew Luck and Chuck Pagano went back to work Sunday when the Indianapolis Colts held their first practice of training camp.

It's a lot different than the last time they worked out at Anderson University. Back then, Pagano was feeling run-down and Luck was still getting a crash-course in playing quarterback in the NFL.

Now, Luck is teaching teammates about the intricacies of the new offense that Pep Hamilton has brought with him from Stanford, and Pagano is feeling well after missing most of last season as he battled leukemia. One thing that hasn't changed: More new faces.

The Colts have nearly three dozen players on their roster, including linebacker Josh McNary, the Army graduate who is expected to arrive in town Monday.
