Benjamin Hall Averaged 7.2 Yards a Carry. On Fourth-and-One, North Carolina Threw It Deep.

North Carolina ran the ball for 214 yards at Clemson on Saturday. Benjamin Hall had 130 of them on eighteen carries, which is 7.2 a crack, and he caught a fifteen-yard touchdown besides. Billy Edwards Jr. completed thirteen of thirty passes for 135 yards, a touchdown and an interception — 43%, in a stadium that had just sat through a thunderstorm.

Fourth-and-one, 1:54 to play, North Carolina trailing 21-20, ball in its own territory. The Tar Heels ran play-action and threw it deep to Jelani Thurman. Edwards overthrew him. Clemson took over, and rather than kneel on it, ran Tyler Brown 34 yards to finish 28-20.

There is a version of that call that is smart. This was not the afternoon for it.

How the thing got close enough to lose

North Carolina was up 17-3 in the second quarter and led 17-6 at the half, and it got there by doing exactly one thing well. Demon June ran in from three yards in the first quarter. Edwards found Hall for fifteen. Aeron Burrell hit a 33-yarder. Clemson's answer through thirty minutes was two Nolan Hauser field goals.

The Tigers then did something quietly useful: they scored twice without kicking. Hauser's third field goal made it 17-9, and Tait Reynolds's 27-yard touchdown pass to Bentancur made it 17-15 rather than 17-16. In the fourth quarter, Gideon Davidson's eight-yard run made it 21-20 rather than 22-20. Two touchdowns worth six points each. We cannot tell from the accounts we could read whether those were missed kicks or failed two-point tries, and it matters less than what it produced: a one-point game instead of a two- or three-point one, which is the difference between a fourth-and-one that has to be converted and a fourth-and-one you can punt from and still be in field-goal range of a tie.

Clemson built the margin Belichick then had to play against, and it built it by accident.

Two and a half hours

At 8:11 of the fourth quarter, with North Carolina ahead 17-15, officials pulled both teams for lightning detected within eight miles of Memorial Stadium. The stoppage ran roughly two and a half hours, through heavy rain. Both teams sat for longer than they had played in the first half.

When it resumed, North Carolina got a 22-yard Burrell field goal and nothing else. Clemson scored thirteen unanswered — a four-play, 68-yard drive for the lead, then Brown's run after the turnover on downs.

It is tempting to make the delay the story and we are not going to. One game is not evidence about what a 150-minute suspension does to a team, and the honest position is that we do not know whether Clemson handled the interruption better or simply played better football for the last eight minutes. What is fair to say is that nobody models this. Conditioning, rhythm, tape review during the break, which staff uses the time well — none of it appears in any preview, and a stoppage longer than a halftime is a variable that arrives four or five times a season and gets written up as weather.

There is a less mystical explanation available and it deserves equal billing. North Carolina was outscored 22-3 after halftime, its edge rush was missing Melkart Abou Jaoude with a hand injury, and Clemson ran tempo at a secondary that had been on the field for most of the third quarter. Tired is not a metaphor. Davidson's 105 yards arrived mostly after the defence had stopped being able to set an edge.

The call

The analytics case for throwing there is real and it should be stated at full strength, because it is the reason coaches make this call.

On fourth-and-one, a defence commits. It brings a safety down, it plays run-first technique, and it dares you to be brave. Play-action off a heavy run tendency in that look is one of the highest-expected-value calls in football — the throw is usually wide open, and the downside of an incompletion is roughly the downside of a stuffed run. The people who study fourth downs have spent a decade arguing that "just pound it" is the emotionally satisfying choice rather than the correct one, and they are usually right. Thurman is a tight end who can run, the defence was sold out, and Belichick said afterward the receiver was open: "it's one of our best receivers going down the field, and he just didn't hit it."

Here is why the general case does not survive the specific one.

The expected value of a play-action shot is a function of how likely the throw is to arrive. Edwards had completed 43% of his passes, in the wet, with a ball that had been sitting through a rainstorm. The run had produced 7.2 yards a carry against this defence all day. And the alternative was not a heroic run into a stacked box — it was one yard, with a back who had gained one yard or more on the overwhelming majority of eighteen previous attempts, behind a line that had opened 214 yards of holes.

Play-action on fourth-and-one also has a cost that the aggregate models do not price at all: it is slow. A run needs a snap and a surge. A shot play needs a fake, a drop, a route to develop and a ball to travel forty yards, and every one of those is a place for a wet afternoon to intervene.

One caveat, stated rather than buried: the accounts disagree about the distance. Pro Football Talk has it as fourth-and-one, twice and in detail, including the 1:54 mark. Sports Illustrated's UNC desk wrote it up as fourth-and-two. Nobody we could read published the play-by-play line. If it was two yards rather than one, the run case is weaker and the throw is closer to right — not right, with this quarterback's afternoon, but closer. The box scores drifted too: total offence is 349 in one account and 357 in another, and Xavier Lewis's sack total for the season is either five or six depending on where you look. That is what happens when a game ends at ten at night because of a thunderstorm, and it is worth saying rather than picking the version that suits the argument.

The falsifiable version, so this is a claim and not a mood: if the staff has read its own team correctly, Hall's carry share should go up against Notre Dame next week and Edwards's attempts should come down. If North Carolina instead throws it thirty-five times, we misread what this coaching staff thinks it is building, and we will say so.

"I won't second-guess him"

The quote is the part that will travel, and it should.

Asked what he saw on the fourth-down throw, Belichick said: "We had a shot at it. There were other options on the plate, but I won't second-guess him. I mean, it's one of our best receivers going down the field, and he just didn't hit it."

Read it twice. There were other options on the plate concedes the point — the staff knew running it was available. I won't second-guess him hands the decision to somebody else, on the record, less than an hour after a one-point loss. And the last clause puts the failure on the throw.

The him is almost certainly Bobby Petrino, North Carolina's offensive coordinator, whose sequencing in the fourth quarter is the thing UNC's own beat writers spent Saturday night questioning. It is possible Belichick meant Edwards, in which case the sentence is kinder and worse. Either way a head coach declined to own a fourth-down call, and the sourcing note here matters: that quotation comes from On3's postgame write-up, which returns a 403 to us and which we have therefore confirmed through two independent retrievals rather than by reading the page ourselves. We could not re-confirm a second quotation attributed to the same session and have left it out.

Head coaches deflect all the time and most of the time it is nothing. It is less nothing here, in the week North Carolina's internal investigation concluded and Steve Belichick — the defensive coordinator and the head coach's son — resigned effective October 27, with Brian Belichick taking over defensive play-calling. General manager Michael Lombardi resigned on September 3. A program that has lost its GM and its coordinator inside three weeks is a program where the question "who called that" has a genuinely unclear answer, and the head coach's instinct on Saturday was to make sure it was not him.

His in-game sideline hit with ESPN's Stormy Buonantony, taken with UNC ahead 17-15 as the lightning moved in, ran about twenty seconds and consisted mostly of the word penalties.

What it costs

North Carolina is 2-1, 0-1 in the ACC, and has now lost eight straight to Clemson; it has not won at Memorial Stadium since 2001. Saturday would have been Belichick's first three-game winning streak in Chapel Hill. Clemson is 2-1 and 1-0, out of an open date, with Dabo Swinney's team having found the thing it needed — 402 yards, twenty completions from Reynolds, and a fourth quarter it won without needing a turnover to do it.

The Tar Heels get No. 3 Notre Dame next. On the evidence of Saturday they have a running game that works, a quarterback who does not yet, and a coaching staff whose fourth-quarter process is now a live question rather than a theoretical one. That is a more solvable set of problems than it looked at 10 p.m. It is also not the set of problems a 17-3 lead was supposed to produce.
