You talk too much about realignment and not enough about other things like the sports themselves or politics.
Just check which board you're on to see the major theme. The realignment issue has been the hot button for the summer, hence the two primary boards revolve around that topic.
I like the Bucs to repeat in the NFC as well. Some key losses, but they're a good example of having a system that works and then plugging in the players needed to put it into practice.
The AFC looks too fuzzy to me. I like the Titans, Ravens and Dolphins, but have yet to see someone break from the pack. Given my tendency to favor stability in team sports, I'd lean towards the Titans right now. Enough playoff experience and big game attitude to compete with everyone else, and the talent necessary to win.
Given that match-up, the Bucs repeat and we must all suffer the sight of John Gruden trolloping around in his jock in downtown Tampa.
