Much has been discussed and speculated regarding who to add and whether a championship game is good for the league. However, very little has been discussed on how best to split twelve teams into two divisions. But with discussion of a league expansion on the back-burner, since Notre Dame turned down the Big 10's last offer, I guess we have plenty of time to discuss how the (eventual) expansion should be structured.
The way I see it, there are two ways to split the conference geographically: East v. West or North v. South. But there are major problems with the East v. West split--something that the Big12 Conference knows too well. All of the traditional "good teams" would be concentrated in one division, the East.
If the conference were split into East v. West divisions, here's what it would look like:
East:
- Penn State
- Ohio State
- Michigan
- Michigan State
- Purdue
- Indiana
- Wisconsin
- Minnesota
- Iowa
- Illinois
- Northwestern
- [New Team Added Here]--Notre Dame, if added, would fit nicely here geographically since they are close to Chicago.
However, if split North v. South, here's how the divisions would look:
North:
- Michigan
- Michigan State
- Wisconsin
- Minnesota
- Northwestern
- [New Team Added Here]--Notre Dame also fits well here.
- Penn State
- Ohio State
- Illinois
- Indiana
- Purdue
- Iowa
Even though this North/South configuration sets-up better for Penn State, I actually prefer the East/West divide. Assuming the Big 10 retains an 8-game conference schedule, it would ensure that Penn State plays Ohio State and Michigan every year, since the Nits would play each team in its division (5 games). Then, the rest of their Big 10 schedule would include a rotation of three Western division teams, ensuring that Penn State would play a team like Notre Dame 3 out of every 6 years, or so.
The Big 10 could also divide the conference based on perceived strength of programs, much like the ACC did with its Coastal and Atlantic divisions--whatever those labels mean. (Side Note: I've never been able to figure out the geographic rational behind the divisions, thus I assume geography did not enter into the calculation.) Either way, geographically or not, I think we could see some interesting pairings within the divisions.
Overall, I think it would be good for the league to add a 12th team. But don't hold your breath. It may be a long time until we see it. After all, a conference championship game makes winning the conference much hard. Plus, it would be harder for a Big 10 team to go undefeated and reach a BCS Championship game. Just ask the 2007 Ohio State team. I'm sure they will tell you that they did not mind sitting at home and waiting for teams ranked ahead of them to lose as they slid their way in the the BCS Championship game last year.
