the Big 10? Really? Did somebody ask this? I guess they don't realize that the Big 10 media market spans from New York to Minneapolis? Talk about a media base.
And, if you are talking Big 10 expansion, don't bank on Louisville. Notre Dame is the first choice, but if the Irish continue to pitter away with being an independant I would look for Syracuse (probably the leagues second choice) or Pitt (Penn State is pushing for them).
Missouri would probably be a fifth or sixth choice IMHO.
