And I have no issue with OSU at 4, just can't see how Iowa is 2. The OSU schedule hasn't been very good to this point, and the Buckeyes didn't exactly roll through the early schedule, but the last three games are MSU, UM, and Iowa. That is where it gets meaty and where if OSU keeps winning will rise in the computer rankings.
BTW, the old BCS computer guys have the top 5 as LSU, Clemson, Alabama, Ohio State, Michigan State followed by Iowa, TCU, Baylor, ND, and Florida. Memphis is 11 ahead of Stanford. Wolfe has Iowa at 1 and Colley has them at 5, none of the other 3 have Iowa in the top 10. Sagarin has Memphis at 26, the other four rankings are 5, 6, 14, and 15. BTW, it is Wolfe that has Memphis at 5 so perhaps these rankings here use a similar methodology as Wolfe.
