Welcome to the NFL thread, 2013 edition. This sport has the shortest playing season of any major sport, and yet it never goes away. In fact in some ways it's even more interesting in the off time, with trades and free agents flying around left and right. Welker to the Broncos...that's an interesting one. The Harvin trade is noteworthy. The NFC West seems to be improving all around. Except for Arizona, naturally.
