Personally, I'd like to see the divisions shaken up a bit. Having OSU, MSU, PSU, and UofM in the East is a bit lopsided. Since the B1G has had a championship game in 2011, only 2x has a west team won (Wisconsin) and it was the first 2 years of the league. Yes, its been a OSU run from hell, but like the old black and blue division in the NFC North, the better teams of the NFC beat each other up and 1 loss to a OSU, Sparty, Blue, or PSU, means your done.
Who would I like to see move to the West from East or visa verca, that I'm not sure of...
