I think I fall into the camp of believing in a stratification effect in college football this year.
I would say that of my top eleven teams, the top four are probably, right now, playing the best football around and are clearly head and shoulders above everyone else.
Of the other four unbeatens in the top eleven, Boise has done what they can and needs a lot of help to reach the BCS title game, but as long as they don't lose late or struggle down the stretch, they should earn a trip to a BCS bowl again.
Wisconsin, Clemson, Stanford and K-State still have chances to make a move, but will also need a lot of help.
Of course, the nuclear scenario is still in play and it will be interesting to see if that plays out. We are just past the halfway point (hence the release of the BCS Standings on Sunday) and so we can now start to look ahead and see who will project where.
And it's funny: I'd actually rather talk BCS than expansion. I never thought I'd write those words.
