What if I told you that with one of the best running backs of this recent Notre Dame era, with one of the most fun running backs in school history, with a tailback with such a high approval rating that he’d sit out the Fiesta Bowl to protect his draft stock, that we’d see maybe the worst ground attack of the Brian Kelly era in 2021?

Okay, maybe it wasn’t the worst–either 2010 and 2013 are the title holders in my opinion take your pick–but it’s at least in the conversation as among the worst rushing seasons.

2021 marked the 4th occasion of the Kelly era where the team didn’t crack 2,000 rushing yards, joining 2010, 2013, and 2016. From that group, 2021’s rushing average of 4.14 yards per carry was 2nd worse behind only 2010.

I know what you’re thinking, don’t blame dear Kyren of all people!

And you’d be right for the most part. During this article for last year’s success rate I mentioned how Kyren’s stock among nearly everyone is so high and yet his rushing stats don’t immediately back up that praise. Well, that dichotomy was even worse for 2021.

Williams was one of 52 running backs to eclipse 1,000 rushing yards and was 51st out of that group with 1,005 yards on the ground. Also from this group, Kyren was tied for 10th worst in rushing average. For the purposes of this article I’ll also note that Kyren’s success rate took a pretty steep dive from 2020, as well. Although, he was a more productive 28th nationally (17th among Power 5 players) in yards from scrimmage in 2021.

2021 Running Back Stats

PLAYER CARRIES YARDS AVERAGE SUCCESS
Kyren Williams 204 1,005 4.93 45.5%
Chris Tyree 56 222 3.96 48.2%
Logan Diggs 52 230 4.42 51.9%
Audric Estime 7 60 8.57 71.4%
C’Bo Flemister 3 10 3.33 0.00%

Note: I use the “old” advanced stat of measuring running success (40% of available yards on 1st down, 60% 2nd down, 100% on 3rd/4th down) because I’m not going back and re-calculating years worth of data. So, for most current success metrics these numbers are actually a bit kinder than you’ll see elsewhere. I generally think 52% (using my numbers) is the starting point for a good back unless you’re really explosive.

There have been 9 Notre Dame players who have carried the ball at least 100 times in a season and averaged better than a 52% success rate* since 2010 and none of those have occurred over the last 5 seasons. We can set aside 2017 because it was outrageously explosive without a very good success rate, so it’s really been 4 straight seasons of mediocre to worse overall results.

*If you’re a fan of Harry Hiestand coming back to coach the offensive line take heart in him being here for 6 out of these 9 performances!

There have been 16 Irish running backs since 2010 who carried the ball at least 100 times and Kyren Williams’ 45.5% success rate from 2021 is the 2nd worst.

With the Jack Coan transfer we anticipated the percentage of running back carries to shoot up over 70% which hadn’t occurred since the 2013 season. Sure enough, the backs ran the ball 71.4% of all rushing attempts for the 3rd highest percentage of the Kelly era.

Additionally, rushing plays of at least 20 yards fell for the 3rd straight season to just 19 across 13 games–that’s the fewest since 2016.

Kyren accounted for 8 of those runs, Buchner 4, Diggs 2, and no other ball-carrier had more than 1 rush of 20 yards or more. Some of those Kyren runs were amazing and highlights of the season but outside those he rushed for 716 yards on 196 carries, or 3.65 yards per rush. There was a lot of nothing on the ground this past season.

There’s no doubt that offensive line struggles, offensive line injuries, and an immobile quarterback absolutely crushed the running game for portions of the season.

Jack Coan’s net yardage came out to -100 yards (pretty much 50% worse than any quarterback who finished with negative rushing yards in the Kelly era) and with sacks removed he had a 42.3% success rate on 26 carries for 91 yards at 3.5 yards per rush. The combination of sacks allowed and not being much of a running threat as a quarterback was really rough this year.

Good news!

The return of Hiestand, plus the return of 4 starters (actually 5 if you want to count Blake Fisher) along the offensive line, plus an extremely mobile quarterback in Buchner is going to bring us some massive improvement in run success rate. Sacks quite literally cannot get any worse than what we saw early in 2021 (Coan was dropped 19 times for -105 yards in the first 3.5 games!!) and the net yardage should spike considerably as Buchner wiggles out of the pocket more often than Coan.

Buchner was only sacked once this season and ran for 346 yards at 7.6 yards per carry and a 57.7% success rate.

The situation in the running back room will be interesting to see how it develops.

Chris Tyree will have a very important off-season coming up. With his turf toe injury he carried the ball 17 fewer times in 2021 than as a true freshman in 2020 while his rushing average dropped by nearly 3 yards per carry, although his success rate ticked up by 0.3%!

I thought his toughness was much improved as a sophomore although questions still linger about his vision and ability to handle the workload of a number one back. Either way, Notre Dame has to find a way to get their speedy back some explosive runs because just 1 run of 20+ yards from Tyree in a season is not acceptable. I’m not sure if we found out when that toe injury happened but Tyree was just 2 of 11 in success rate from the Wisconsin through the Navy games, or basically half the season.

Some people are extremely high on Logan Diggs. He had the “advantage” of missing out on the first 5 games through Cincinnati when the offense and offensive line were struggling their most. He looked really strong in back-to-back games against North Carolina and Navy (78.9% success rate across 19 carries) but was only at 36.3% success rate in all other carries with a propensity to be too patient behind the line and get dropped for little gain, or worse. For me, I don’t think we’ve seen enough to know much other than Diggs will probably be solid.

The tiny glimpse of Audric Estime offered some hope for the future, too. There’s also a very real possibility that incoming freshman Jadarian Price shoots up the depth chart as a battle for starting reps begins this off-season. However, we have to remember that with Buchner at quarterback the amount of carries going to running backs is going to decline so we could be back to an offense where the 3rd back really isn’t playing much of a role outside of garbage time.
