I think Fav Farvra Fav-ray whatever is done. I think he'll "retire", buy a few new suits, and head to the commentator booth. Why do I think that? Because one of the female sideline reporters got to him while his guard was down and he sort of laid out what he's thinking about.
Basically it seemed to come down to the fact that although he's still on his game, it's the off-season that's getting to him. As he gets older, he has to work harder and harder during the off-season to keep up, and he's missing his kids growing up because of it. I know a few fighter pilots and WSOs who made the same kind of decision, and they sounded pretty much the same when talking about it.
He really sounded like a guy who's tired of the grind. Yea he's still a great player but it sounded like he doesn't think he wants to spend another year of his life prepping for 16 more games at the expense of his family. The work/life/fun/pain balance might not be right anymore. At least, that's what it sounded like when he was talking to the reporter. And right after he said it, he realized that he'd spilled the beans earlier than he planned and he quit talking. But before he clammed up, he sure sounded like a guy who was ready to move on.
