I saw on ESPN this morning that Peyton Manning speaks Gaelic to his offensive linemen. They don't know what he's saying, but as long as the defense doesn't know either they're cool with it.
I could be wrong, but I think ESPN and Peyton Manning were having a little fun.
I could be wrong again, but I think this is a story that is supposed to convey the close relationship between McFadden and Etheridge. I think it's supposed to be touching and show the will power that one can have when playing for something more than himself.
