ND-USC: A Rivalry Recalibrating

The calendar has moved again, and this time it has moved into a stretch where the ambient signal I have been reading all summer finally has some real football sitting next to it. Chapter 10 left us on the September 11 GDELT spike, honest about the fact that a flat line of ones is not enough to hang a chapter on. Two weeks later, the picture has changed, not because the ambient wire got louder — it did not — but because the pageview line for Notre Dame did something it has not done all season.

Here are the numbers. On September 20, according to the daily pageview counts published by the Wikimedia Foundation, the Notre Dame Fighting Irish football page drew 5,638 views. That is more than three times what it drew on September 18, which was 1,690, and more than three and a half times its September 17 total of 1,562. September 15 was 1,594. September 16 was 1,548. September 19, the day before the spike, was 3,360 — already twice the weekday floor, and then the number essentially doubled again into Saturday.

“Hello Irish fans, I’m hoping you can help me find a very old highlight video of Notre Dame’s 40-37 comeback win over Michigan State in 2006. This particular video was set to Eminem’s “Lose Yourself.” I probably watched…”

That is the shape. A quiet weekday plateau in the mid-fifteens to mid-sixteens, a Friday step up into the mid-threes, and then a Saturday number that dwarfs anything the summer window ever produced. For context on scale: the Notre Dame page's summer weekday floor, back when Chapter 8 was walking through the August pre-Week-0 stretch, sat above a thousand and felt like a story. The September 20 number is more than five times that floor.

The USC line over the same September window is worth putting next to it, because the shape is different in an instructive way. From September 15 through September 18, the USC Trojans football page drew 1,060, 960, 976, and 1,019. That is a weekday line that does not really move — a program page ticking along at roughly its baseline, with no meaningful mid-week bump. Then September 19 brought 2,318 and September 20 brought 2,625. USC's Saturday number roughly doubled its Friday number, and its Friday number roughly doubled its weekday floor. The Notre Dame page did the same doubling twice.

Both lines spike on the same days. The Notre Dame spike is simply much larger in absolute terms.

I want to sit with that difference, because it is the first time in this thread that the pageview evidence has told me something other than what the summer told me. Through July and August, and as Chapter 8 laid out in detail, the Notre Dame page more than doubled USC's page on quiet days with no game to force the comparison — a curiosity gap that ran ahead of the news. Chapter 9 then watched USC's line briefly triple Notre Dame's on August 29 as Week 0 arrived. What we have now, in the third week of September, is neither of those shapes. Both programs are lit up on the same weekend. Notre Dame is lit up more.

The one thing the ambient signal is doing in September, and doing all by itself, is behaving like a schedule.

That is worth writing down as a sentence you can hold onto, because it changes what this thread is measuring. In June and July, the pageview line was a proxy for offseason curiosity, which was the only thing anyone had to look at. In late September, with games being played, the pageview line is mostly telling us that people look up football teams on Saturdays. The interesting residue is what the lines do around the Saturdays — the mid-week floor, the Friday ramp, the gap between the two programs on quiet days — and there the September evidence is still pointing the same direction the summer did. Notre Dame's weekday floor is meaningfully above USC's weekday floor. USC's baseline is not accelerating into the season the way you would expect from a program with the kind of recruiting momentum its wire has been carrying.

The GDELT article-count line, for what it is worth, kept doing what Chapter 10 said it was doing. September 15 registered 2 articles for the Notre Dame query. September 16, 17, and 19 each registered 1. September 22 registered 2. September 23, 24, and 25 each registered 1. USC's GDELT query surfaced a single article on September 18 in this window. This is the same flat floor we walked through last chapter, and I am not going to pretend it is telling me more than it is telling me. What it is telling me is that whatever pageview surge Notre Dame's page saw on September 20 is not showing up as a proportional national-news surge in this particular measurement — which either says something about the specific GDELT slice being narrow, or says the Saturday interest is fan interest more than news interest, or both.

The Wikipedia edit history around the same window is the small detail I keep coming back to. On September 16, the Notre Dame Fighting Irish football page took six edits and added 908 bytes in a single day. On September 17, it took two more edits and added 43 bytes. On September 21, two more edits and 31 bytes. Somebody, or several somebodies, was updating the page in the days leading up to that September 20 spike. The USC page took two edits on September 21 and added nine bytes. That is not a page in the middle of active revision; that is a page getting a small touch-up.

None of this is a scoreboard. I want to be careful here, because the shape of what I do not know is larger than the shape of what I do. The pageview data does not tell me what people were looking up when they arrived at the Notre Dame Fighting Irish football page on September 20. The GDELT counts do not tell me anything about which stories they represent. The edit deltas do not tell me what was actually being edited. What the three signals together do tell me, at the level this thread can honestly speak, is that Notre Dame's Wikipedia footprint in the third week of September behaved the way you would expect a program page to behave when the program is in-season and the program is being watched. USC's footprint behaved the way you would expect a program page to behave when the program is in-season and being watched at a lower amplitude.

That is the update. The thing I have been tracking all summer as a curiosity gap has not closed. It has narrowed in relative terms on Saturdays, when everybody's pages spike, and it has held on weekdays, when only the interested show up. The interesting question for the next chapter is whether the weekday floor for either program moves before the calendar turns to October — because that is the number that is not being pulled around by the schedule, and it is the number this thread has actually been built to read.
