GREENSBORO, N.C. — As superior statistical analysis and its attendant new know-how proceed to reshape how sports activities actions are understood, watched and even carried out — when to punt on fourth down in soccer, the place to put a baseball workforce’s infielders and the proper strategy to assemble a worthwhile basketball workforce — these new numbers moreover create a vexing downside:

How to account for what superior algorithms cannot make clear.

The thirst for information is such that one necessary set of college basketball data that may help determine the self-discipline for this month’s N.C.A.A. match, Ken Pomeroy’s eponymous KenPom rankings, consists of a metric to clarify when points do not actually go by the numbers.

Pomeroy has a moderately analog time interval for it: luck.

“Luck is basically performance in close games,” Pomeroy said. “People generally don’t like the term ‘luck’ — that’s the feedback I get. Technically, I’d call it ‘randomness’ or something a lot more wordy, but that doesn’t fit well above a column.”

In transient, KenPom’s luck subject considers the distinction between a workforce’s file and what the data would rely on it to be. If a workforce’s file is finest than its predictive numbers, it is lucky. If it is worse, then it is unlucky.

This season, in protecting with the KenPom rankings, no workforce amongst the 353 Division I school males’s basketball packages has been luckier than the University of North Carolina at Greensboro.

The Spartans resemble a workforce one could rely on from a coach, Wes Miller, who transferred to North Carolina as a walk-on, then earned a letter on a nationwide championship workforce and eventually a spot in the starting lineup. They are resourceful and determined, and have the ethos (and the recruiting funds) of an underdog.

Greensboro has a 28-6 file — the most interesting in program historic previous — and accomplished second in the Southern Conference, behind Wofford, which was ranked 20th in this week’s Associated Press poll.

Did luck have one factor to do with it?

Miller, pulling up a folding chair sooner than a present observe, reacted as one could rely on. He praised Pomeroy as “a genius,” expressed fascination with analytics and said there have been others on his employees who delve deeper into the data to provide the most salient particulars about the Spartans and their opponents.

Then he assumed a defensive stance.

“I’m not a mathematician,” he said. “I’m a basketball coach who’s always attempting to find out an edge to help me coach increased. But there’s under no circumstances been anybody that may put a amount on will and togetherness of group.

“There’s one thing that’s taking place in our video games that’s indescribable to his knowledge that’s getting us over the hump,” Miller added. “That’s toughness. That’s the ability to win close games. The proudest I ever am as a coach is when we have an awful shooting game or we have an awful offensive game and things don’t go our way and we still find a way because our team was able to dig down and figure out a way to get over the hump.”

Francis Alonso, a senior guard from Malaga, Spain, who’s the heartbeat of his workforce, put it one different technique: “There’s this saying — it’s champions’ luck.”

Alan Castel, a psychology professor at U.C.L.A. who analysis memory and metacognition — how we think about our pondering — said that whereas confidence (or the lack of it) is a fundamental facet of athletic rivals, it is often misplaced.

“The human mind doesn’t rely on big data,” said Castel, whose evaluation has debunked the hot-hand precept — the notion that a workforce should get the ball to a shooter who’s on a scorching streak. “We’re prone to rely on illusions and small sample sizes and what we want to think.”

If Greensboro’s Spartans are the luckiest workforce in the nation, he said, they deserve a few of the credit score rating for it.

“To be lucky, you need to put yourself in a situation,” Castel said. “To win the lottery, you need to buy a ticket.”

Or, he added, to win the N.C.A.A. match, you need to get in. And to do that, the Spartans almost truly would require a little further luck.

Some years in the previous, a résumé like the Spartans’ may want regarded glossier. They have a glowing file, are 7-0 in video video games decided by 5 elements or fewer and have been aggressive in defeats at 10th-ranked Louisiana State (97-91) and sixth-ranked Kentucky (78-61), a recreation that they led with decrease than 9 minutes left. But they misplaced to Wofford twice in the widespread season — by 29 and 30 elements — and for a third time on Monday night, 70-58, in the Southern Conference match championship recreation.

Yet it is this profile — a workforce that has squeaked earlier unhealthy teams, competed in opposition to good ones and been pounded solely twice, by the most interesting workforce in its conference — that explains why Greensboro’s luck subject is +.175, which, if it holds until the season is over, may be the highest of any workforce since 2013.

What that decide means, Pomeroy said, is that in a luck-free environment, the Spartans’ worthwhile proportion may be 0.175 lower than it is. As a finish end result, they’d have six fewer victories — and a 22-12 file — with none luck.

There are real-world penalties: Through Tuesday’s video video games, Greensboro ranked 81st in KenPom’s common rankings, lagging behind East Tennessee State (71st) and Furman (55th), in opposition to whom they blended to win 4 of 5 video video games this season. (The N.C.A.A.’s new NET metric, which the match selection committee is using to guage teams this yr, is simply barely kinder: It has the Spartans 58th.)

Once the N.C.A.A. match begins subsequent week, with a broad spectrum of colleges from spherical the nation, a clearer picture will emerge of whether or not or not teams which have been deemed to have liked metric luck have punched above their weight all season.

The Spartans, at this stage, would ponder themselves lucky to have the likelihood.
