How Peyton Manning is different

— -- Working with and coaching Peyton Manning, the NFL's new record holder for most career touchdown passes, is an interesting experience.

Manning may know everything you know. And, he may know more than that, too. If you have too much of an ego, it might be an issue because Manning will remember everything he's seen and everything you've done.

And it's one of the most intriguing things about one of the most interesting characters the NFL has seen.

"It is very difficult to describe him unless you've worked with him," said Detroit Lions coach Jim Caldwell, Manning's former quarterbacks coach and head coach with Indianapolis. "You call those guys out in Denver, and I guarantee you, start talking to those guys that have worked with him.

"It's different."

How different? Those who have spent the most time with Manning try to explain exactly what makes Manning operate.
