Top contenders to host Game Day next week appear to be Columbia, MO (#6 Oklahoma vs #21 Missouri or Stillwater, OK (#5 Nebraska vs #20 Oklahoma State). There is also Auburn, AL (#9 LSU vs #7 Auburn), but Auburn just hosted a few weeks ago, so that doesn't seem logical.
The following week, the biggest matchups to consider would be Lincoln, NE (#2 Nebraska, yes i said it! vs #15 Missouri) or Iowa City, IA (# 12 Michigan State vs # 14 Iowa).
For now it's in our best interests if Mizzou and Okie State win this week to pump up the computers for the BCS. The Huskers IMO received a national boost last night with K-State's 59-7 thrashing of Kansas.
