Take away all of the politics, and I miss the Big 12. It was fun hating Texas and Colorado. Every week I knew who everybody was playing and it was fun to see if CU lost, etc. It will take a long time, but I don't feel the same about the Big 10. Iowa is our "rival" but I never know who they are playing and really don't care.
I think overall the Big 10 was important for NU, but from a football stand point I don't enjoy it. In fact, I don't like all of the conference re-alignment in college football. I don't think it has been good for the game.
