There have always been people involved in picking who gets in the playoffs. Even with the BCS.
I agree that Alabama has a good enough resume to be in the playoffs this year although I think Ole Miss should be there instead. If Alabama plays well in the playoffs has nothing to do with putting them in it. The way it looks now, Alabama will go to South Bend and play Notre Dame in the first round which they are only a 3 point dog in, so they can win that game. The second round would be against Boise State, which would have Alabama a double digit favorite.
I really like this 12 team playoff, but I think automatic bids and seeds are not at all a good idea.
