When a team is hovering around a three-touchdown underdog, a lot of match-up and scheme questions go out the window in favor of simple ones – How do the Irish stay competitive with a historic Alabama offense? What would the path to an upset victory even look like? What moves give Clark Lea and Tommy Rees the best chances to win their matchups?

In an era of offensive explosion, where the single most important unit is an elite passing game, Alabama has fielded a historic attack (despite a QB with little hype entering the season). The stats are all insane, but to keep it simple, they’ve been better than last year’s historic Joe Burrow attack at LSU. The Tide average 4.38 points per offensive drive (excluding garbage time), and gain 73.4% of available yards (last year the Tigers were at 4.1 points / drive and gained 69% of available yards).

To give Notre Dame the best shot, Brian Kelly needs to embrace an underdog strategy. In broad terms, this means maximizing variance – if these teams play 10 times, Nick Saban is getting a Gatorade bath at the end of 8 or 9. But over the course of a smaller sample – a game, or ideally just ten possessions – the Irish can take advantage of randomness and swings in quality of play.

The goal: maximize variance

The challenge is that maximizing variance in football is complicated. In basketball, an underdog can slow down the game, strategize into giving up certain types of shots defensively, and shoot a ton of threes to introduce all kinds of variability. Shortening the game and increasing your range of outcomes can be done in a somewhat coordinated way. Failure on a possession (a three-point miss) has limited impact on your opponent’s next possession. But in football your goals are often at odds – an aggressive passing game that gives you a better chance of scoring can create a high-possession (variance-lowering) game.

So how should the Irish try to maximize variance against Alabama:

#1: Balance possession and aggression on offense

The Irish could take some pages from the Navy book of competing as an underdog – the modern triple option is built to create long, time-consuming possessions when at a talent disadvantage. Offensively, chewing up the clock is ideal, but this doesn’t necessitate a run-dominant attack. Burning clocks must be balanced with trying to create touchdowns, which you can’t expect to do with a run-run-pass strategy and pounding Kyren Williams into the line.

Tommy Rees can leverage a mix of passes that are more ball-control oriented (screens, high percentage play-action looks, swing passes) with deep shots that are high-reward and relatively low risk. The optimal underdog strategy is about opportunism, not conservatism– when the clock is running, milk it, and if you’re risking stopping it, take shots that make it worthwhile.

For the Irish to be successful against a Bama defense that’s shown more warts in the passing game than on the ground, this requires a multi-dimensional effort. Play-action and early deep shots may soften a defense that is likely anticipating a run-heavy attack. When running, stress the defense to account for everyone. In the Clemson game, Ian Book had zero successful runs on four attempts that netted one yard. Book’s legs and the threat of receivers in the run game will be necessary to open things up for Williams and Tyree.

#2: Tempt the Alabama offense into playing your game

Playing a low possession game isn’t solely an offensive strategy. Bait Bama into playing into a short contest– do not stack the box, guard against the pass, and bend but don’t break. This doesn’t mean you are going to stop Alabama, but letting Najee Harris go for seven yards per pop while chewing clock is better than allowing Mac Harris dropbacks that easily average ten yards per attempt and introduce a greater chance for quick-strike touchdowns.  Make Bama go on 10-play drives –  every play counts and is another opportunity to strip the ball, draw a penalty that increases your chances of a stop, or a limiting the damage to a field goal. The most important goal is limiting explosive plays.

A great example of this strategy working effectively was this year when the Bills faced Patrick Mahomes and the Chiefs. Buffalo played their linebackers and safeties deep, and Kansas City flipped their usual run-pass ratio as a result (from 60/40 passing to 40/60). Clyde Edwards Helaire ran for 160 yards but had the same number of carries as Mahomes had pass attempts (26). Both teams had just 9 possessions, and the Chiefs only scored 26 points, giving the Bills a real shot. Unfortunately, their offense failed to take advantage, averaging just 4.1 yards per play. It’s not a pleasant experience, but that’s the blueprint.

#3: Steal possessions in any way possible

This isn’t complicated – as an underdog, every single drive must be maximized. One cheap way to steal a possession is making sure you have the ball near the end of each half, ensuring you have at least one more total possession than the Tide. Try a surprise onside kick – what’s thirty yards of field position compared to the upside of a stolen possession?

Notre Dame should be going for it on fourth downs early and often (and importantly, planning to do so in advance, enabling more options on 3rd downs). A key mistake many underdog coaches make is waiting too late to take chances. Risks not taken early in the game (say, an early 4th and 1 from their own 35) usually translate into forced risks taken later (going for it on 4th and 10 down many scores in the second half).

Underdog coaches also tend to believe too much in early success or their teams ability to execute out of a talent disadvantage, believing it will continue. Getting a first half stop or two on Bama should be viewed as a massive win but not a sign that future drives will result in anything but touchdowns. Decisions on offense should be made under the assumption that Bama will score a touchdown when they get the ball – don’t settle for field goals unless the fourth down chance is abysmal.

There is no magic formula for beating a team like Alabama. Their weaknesses are on the margins and the Irish aren’t ideally equipped to take advantage of the Tide’s penchant for giving up long pass plays to super fast receivers. Usual tenants of good strategy apply, and Notre Dame simply has no margin for error. They need to play well and win all the little areas – turnovers, penalties, field position, and converting scoring chances to touchdowns.
