TEMPE, Ariz. (AP) - A trip to Duke University to help Peyton Manning work his way back from neck surgery turned out to be just as beneficial for his longtime offensive coordinator Tom Moore.

Knee problems had forced the coach into retirement, although he doesn't like the word, and as Moore tells it, when Duke coach David Cutcliffe saw all the pain the old coach was dealing with, he said, ``We've got to do something about that.''

A visit to the top specialist in the field at Duke University led to the replacement of both knees. Now, the 74-year-old Moore feels like he's 50 again, and chomping at the bit to get to work as the right-hand man of new Arizona Cardinals coach Bruce Arians.
