The first AP and coaches' polls of the season are out, and our wonderful Wildcats are ranked 20th in both flavors. But there are some differences between the two, as is usually the case, and we figured we'd do the intelligent thing: split the difference.
In the following table, which I tried really hard to make sortable but apparently there's something not working right -- probably the tie notations, the negative number format, the null cell notations, and the notes for Penn State and North Dakota State. By the time I realized this, I had basically decided it wasn't worth trying to fix; I'll see if it works better next week. But I digress.
There's the AP poll to the left, the coaches in the center, and the combined poll to the right. What I did, however, was not to simply add the points together. There are a few fewer voters in the AP poll, so I broke things down by points-per-ballot (the PPB column under the combined heading) for each poll separately, then added those figures and divided by two. I did this rather than simply doing raw points per ballot in order to very, very slightly devalue the effect of single points in the coaches' poll to reflect their slightly larger ballot count. (You'll see an example of this toward the end of the article.) PPB also has the benefit of clearly illustrating the gaps between teams; if one team has 15 PPB and another has 13, you know that the voters actually have them separated by two places in the poll even if they're next-door neighbors. I've also extended the poll all the way to the end, rather than just stopping at 25; the reasons for this should be obvious when you consider that Texas is ranked in one and Louisville isn't, and vice versa.
Penn State and North Dakota State are special cases. Neither is eligible for the coaches' poll, for two entirely different reasons, but received votes in the AP. I could have taken the points-per-ballot from the AP poll and just used that without factoring in the zero points-per-ballot from the coaches. That seemed to be as nonsensical as the other option, so I went with the one that reflects reality. If you care, had I chosen the other method, Penn State would move up to 31st from 37th in the combined poll, and North Dakota State would move up one spot from 49th to 48th, so it's not like it matters much.

Chaos in the chase lap
There is a huge gap between #1 Florida State and #2 Alabama. The Seminoles are receiving over two more points per ballot than the Tide, which you might think sort of means the voters as a whole think Alabama should be third. Of course, what it really means is that Alabama, Oklahoma, and Oregon are a big jumble. In the AP poll, Alabama only leads #4 Oklahoma by 34 points, which is barely half a spot; in the coaches' poll, Alabama's lead over #4 Oregon is more pronounced but still only 74 points, barely more than a full spot. When you combine them, just on raw vote totals the Tide only lead #4 Oregon by 77 points -- across 121 ballots, so yeah.
Auburn is on an island in fifth, more than 1.5 points per ballot back of Oregon but just a hair under two PPB ahead of Michigan State. Georgia's hot on Michigan State's tail, with only 12 raw votes across both polls separating them -- even though Ohio State is between them in the coaches' poll. Why the dropoff to Ohio State in the combined listing? Because they're way, way behind Sparty in the AP, that's why. As a result, they're a full spot behind Georgia in the combined.
When polls don't agree
Next, after a perfectly normal gap to Baylor, we have a huge jumble from 10-13. The problem with those teams below Baylor is that they're scattered all over the place. Texas A&M is ninth in the AP, but 13th in the coaches' poll. Poor LSU is 13th in the combined poll despite being 12th in both actual polls, and that's because they're barely ahead of A&M with the coaches while being three whole spots back of the Aggies in the AP. UCLA and Stanford are the other components of the traffic jam, and all four of them are separated by barely more than half of one poll position. Only 70 points separate #10 UCLA from #13 LSU... again, across 121 total ballots. That's close, baby.
Where there is a traffic jam, there is a huge gap in back, and that's what we've got to #14 USC. They're three whole positions behind LSU here, so the perception line between the Trojans and the top 13 is, to put it mildly, massive. Less massive, but still pronounced, is the gap between USC and #15 Notre Dame, also nearly three positions back. Does that mean there's another pileup on the way? You'd think, but no; Ole Miss and Arizona State are tightly together a slot back of the Irish, but it's another decent jump down to get to Wisconsin and Nebraska, paired up at 18-19. Those two are separated by one single point across both polls, with K-State trailing fairly close behind in 20th, right where they're supposed to be.
The rest of the relevants
South Carolina sits basically two spots back of K-State. Because the coaches aren't as excited about North Carolina as the writers, we've got a small bunching behind the Gamecocks. The Tar Heels have half a length on Missouri and Clemson, who are fairly close together. Texas finishes the traditional top 25, with Louisville right behind; with one ranked in the AP and the other in the coaches' poll, that makes perfect sense. Of the "also receiving votes" group, only Louisville, Oklahoma State, and Florida received over one point per ballot, though Mississippi State is just shy of that mark. Technically, Mississippi State did receive 121 points off 121 ballots, but the slight adjustment due to the different number of voters makes a difference here; Clanga was more highly valued by the coaches, who have more points to distribute than the writers. Switch a couple of 25th place votes from the coaches to the AP, and they're over 1.000.
The rest... of the rest
There's a group of teams who at least a third of the voters thought deserved to be ranked: Duke, Michigan, Washington, BYU, TCU, Penn State, and Iowa. Penn State is, of course, a special case; in the AP poll, they're tied with Mississippi State at 29th, but they don't exist at USA Today. Minnesota could be a few spots higher, except they got no votes in the AP poll to go with their 16 points in the coaches' ranking; Tennessee, right behind them, has the opposite problem. And then there's Arkansas, which looks a little weird in the table. They're included because they finished dead last in the combined ranking of the preseason polls, with one solitary 25th-place vote in the coaches' poll, and that's why it looks like they have no delta despite losing that vote; they were tied for 55th last week, and this week 54 teams received votes in one poll or the other. So they're still 55th. Woo Pig Sooie!
Rockets and lead zeppelins
The big winners on the week were Penn State, Tennessee, West Virginia, Arizona, and Rutgers. All four improved their positions by 10 spots or more from last week, which is doubly impressive for the Nittany Lions and Vols as they got no help from the coaches. South Carolina, Boise State, Northwestern, and Miami all took severe falls, but the movement championship this week goes to Central Florida. The Knights went from being the first team out of the AP preseason poll and 28th in the coaches'... to not getting a single vote from anyone this week. As a result, they fell 22 spots in the AP, 25 in the USA Today, and a mind-boggling 27 in our combined ranking. Woof.
