Of course the Titans want him. He would complete their collection.
Honestly, I'm a little shocked too. Apparently Miami didn't even make the finalist list and I figured they'd be frontrunners. I guess that is what shocked me most... them not even being on the final short list.
Most have said Miami has something there that is running away coaches and players, not sure if it is the management or what, but I have heard it stated that the same thing that made Jeff Fisher not sign to coach there is the same thing that turned Manning away.
I think he will be a good fit in Denver, they will need to get a reliable slot receiver though, and quick. Those Receivers really know how to drop passes.
