When the Packers lost that game, I was 99% sure that he was going to return. In previous years, as in the last 1, 2, 5(??!!) years that he has been contemplating retirement, I had always thought it could go either way.
But after such a successful season, with a young team with such potential, I thought it was a sure thing he would be back. Kudos though to him for making the decision to spend time with his family. It's just that, of ALL the seasons, I wouldn't guess this would be the last of his.
Tough guy though, gotta admire that. A true love for the game... very inspiring.
