This is the Depth Dossier: the Boston College Eagles, Week 9.

Let's start with the number that says everything: Duke 47, Boston College 2. And BC's only points came on a blocked extra point return. Everything else was self-inflicted.

Fifteen penalties for 129 yards. Six sacks allowed. Two of 13 on third down, with zero fourth-down conversions. Boston College drove inside the Duke 40 six times in this game and came away with nothing six times.

Quarterback Mason McKenzie started and struggled early, losing a fumble, and got pulled after a failed fourth-and-nine. Grayson Wilson came in and lasted ten snaps before getting stripped. Femi Babalola closed things out. Meanwhile, Duke running back Nate Sheppard ran for five touchdowns against a defense that couldn't hold its gaps. After the game, the analytics service CollegeFootballData put BC's win expectancy at 0.8 percent, and honestly, that feels generous.

Let's talk about how it actually got this bad, because the penalties set the tone early. Boston College had eleven penalties for 94 yards before halftime alone. Cornerback Syair Torrence drew an end-zone interference call that set up Duke's first touchdown. Defensive back Danny Edgehille picked up back-to-back penalties, including an unsportsmanlike conduct call that turned a likely first down into third-and-23. A roughing the passer call and an offside penalty extended another Duke scoring drive.

Head coach Bill O'Brien pushed back on blaming the officials, saying, "We didn't lose because of officiating." Defensive back KP Price backed that up, saying, "We can't look at the refs and ask them why they called it." Fair enough, but the math still tells the story.

And then there's the finishing problem. Those six trips inside the Duke 40? Zero points. Boston College went 0 for 6 on third down in the first half, and all four of its fourth-down attempts died inside Duke territory.

Here's the strange part, statistically. By the advanced numbers, Boston College and Duke were nearly even on a per-play basis. But Duke hit far bigger plays when it counted, including a 54-yard touchdown run by Sheppard. It wasn't that Duke outplayed BC snap for snap. It just made the big plays stick.

One historical footnote worth mentioning: that blocked-kick return was the first defensive extra point Duke has allowed since 1999. It was also the entirety of Boston College's scoring on the night.

Now, onto the depth chart, because this game may have opened up a real quarterback competition. No injuries came out of Durham, but all three quarterbacks who played raised questions.

McKenzie started and went 9 of 17 for 87 yards with a lost fumble, completing passes well below where you'd expect given the situations, before getting benched. He admitted afterward it was "tough, especially in the first half."

Wilson came in for just ten snaps, went 2 of 5 for negative one yard, and got strip-sacked on his one extended look.

Babalola finished the game and, by the numbers, was actually the most effective of the three, going 3 of 5 for 49 yards on just eight snaps. The Boston Globe noted he "showed flashes." Nothing's official yet, but if the coaching staff is looking for a reason to open up the quarterback competition, Babalola just handed them the best tape from this game.

Up front, the offensive line allowed those six sacks while cycling through ten different linemen, which tells you the coaching staff was already searching for answers during the game itself.

The one clear bright spot was defensive back Carter Davis, who had the blocked-kick return, a tipped interception, and five tackles. He's the riser to watch.

Going forward, keep an eye on the quarterback snaps and any further shuffling on the offensive line as Boston College tries to clean up a performance that its head coach says is on him to fix.
