Well, there wasn’t too much shakeup in the polls at the very top, because no teams lost at the top. Everyone held serve, until we get further down in the top 10.
Wisconsin might actually be good after a surprising 30-6 whoopin' of Michigan State. Personally, I feel this spin move should earn them at least a few No. 1 votes, but that’s just me. In the other biggest ranked matchup of the day in Week 4, Tennessee came back with furious vengeance in the second half to beat Florida for the first time in 11 years.
Elsewhere, Texas A&M and Ole Miss won big games over ranked foes Arkansas and Georgia, respectively.
Below is an update of the rankings after Week 4. No, the Playoff rankings aren’t out yet. Be patient, young grasshopper, Nov. 1 will be here sooner than you think. After the table ,you’ll find a handy rankings explainer too.

The four rankings used here
The Associated Press Top 25: The longest-running and best-respected human poll. Didn't have any official bearing on the latter years of the BCS, and doesn't have any official bearing on the Playoff. Most outlets (including SB Nation) will use the AP's rankings as the standard until the committee takes over in November, though. You can expect these rankings to drop early Sunday afternoon.
The USA Today Coaches Poll: Formerly part of the BCS, and now just a poll. It tends to react more cautiously than the AP's. Though polling athletic departments in order to rank other athletic departments is dubious, we still want multiple human polls in here, and this is the other big one. These rankings typically come in around noon.
The Massey computer composite: A collection of every rating out there. We include the latest version as of publication. (It does also include the two human polls, but they can't sway it all that much.)
Bill Connelly's S&P+ ratings: SB Nation's favored advanced stat, which arrives a bit later than the others. An important thing to keep in mind: for the first few weeks, it also factors in preseason projections. It'll look pretty weird early on, but it's proved to be a very strong predictor against the Vegas spread over the long term.
