COT Numbers Don't Tell The Story

I knew this would happen. We now have in T.J. McCarthy a writer citing NASCAR scoring loop data to make a COT race look more competitive than it actually was. McCarthy compiles scoring loop data on "quality" passes and shows where there have been three races where there were more "quality" passes with the COT than with the "older" flush airdam/spoilered cars.

Scoring loop data is inherently deceptive because it counts as "quality" passes any kind of position change in the top-15, even if lapped cars pass cars running in the top-15 - which happens a lot at Darlington as cars short-pit and get fresh tires on the track's notoriously rough surface. There is always position passing and lapped cars interfering with lead-lap cars outside the top-ten; it's in the top ten that passing matters most, and at Darlington the top ten hardly changed hands all race long and was usually spread out over nearly half the track, a pattern seen at all the other COT races so far.

And as far as lead changes go, the COT hasn't made any kind of dent in the sport's Dead-Lane Era. 21 lead changes in a 500 mile race is hardly impressive unless the lead bounces around several times a lap, as has happened at places like Pocono - the 1990 Summer 500 had 21 official lead changes and over a dozen unofficial ones, including four lead changes on Lap 117 alone and three on Lap 180 - but which manifestly didn't happen at Darlington or any other COT race. NASCAR counted 673 "quality" passes at Darlington - but there were only 21 lead changes, and nowhere did the lead change more than once a lap.

This is where scoring loop data is worse than useless. First of all, these stats are compiled for all those fantasy geeks that have permeated pro sports' fanbases like poison over this decade - that hilarious NFL Network ad with the fantasy geek who can't pronounce T.J. Houshmenzedah's name isn't entirely exaggerating what fantasy geeks are about. Second, as McCarthy is doing, NASCAR is using this data to make its races to be better than they actually are.

"Give it time," McCarthy claims. "The smartest people in racing are working on a solution." McCarthy makes the classic mistake of flattering John Darby, Brett Bodine, Gary Nelson, and others involved with this project as smarter than they actually are. The COT has gone through over a year of testing and now five races and it has shown zero improvement. That fantasy-geek data cited by McCarthy doesn't tell the real story, which is that passing is down with the COT, as the car cannot turn, pushes worse in dirty air than the older car, and is hamstrung from improvement by its fundamentally unsound design. You can't get good racing out of a racecar design with a bulky roofline, short nose, gapped airdam, long rear deck, and use of a wing.

There was also a lot of nonsense about how "tough" the COT was, though that gets debunked here. Few noticed how much more sensitive to spinning out the COT proved to be at Darlington - when McCarthy starts talking about how the leaders all slapped the wall and kept going, "tell me that isn't old school." No, it isn't, because the COT resisted turning. Not being able to turn is not old school.

The COT "has lost 30 to 40 percent of the handling," noted Jimmie Johnson after the Southern 500. With so little passing at any of its races despite Tom McCarthy's pathetic attempt to use deceptive scoring loop data to argue otherwise, the car has had enough time to prove itself, and it has failed.
