Hi--long time lurker, first time poster.
I've been thinking about Manning's motivations. This is a man who has no life outside of football. What's he looking for? Obviously, money is part of the equation, but I don't think it's everything, or he would've brought his agent along on the visit.
I think Manning is really looking for two things: another Super Bowl ring, and a future post-retirement in football. I think he'll chafe being away from the game and he knows it. So the question for him would be, does he stay involved via the management route a la Elway or the coaching route?
We all know that Manning was essentially his own Offensive Coordinator in Indy. What if Denver said, "hey, we know McCoy isn't going to be around forever. How about you play for us and when you're ready to retire from the playing, you can become the OC?"
Wouldn't that be tempting?
I think it also would help explain Denver over some of his alternatives. If he just wanted a ring, there are better choices (New York, for one). But if he wanted to step into coaching, then working with a defensive coach like Fox who gets along with players and an exec like Elway would be a great way to do so.
