Two weeks’ worth of charts reveal a defense that, while young and far from perfect, may be starting to figure things out.
As a reminder, the little number next to each player’s name is the total number of possessions in which that player participated. Playing one play in a given series counts.
A few notes:
- Tom Allen said before the season that he planned to play more guys on defense this year as a means of limiting late-game fatigue. So far, he has been true to his word, with 29 players seeing action against FIU and 28 against UVA. But the total number of players seeing the field isn’t that different than what we have seen before from Allen. In his first two years, we frequently saw IU rotate in more than 20 players on defense. The big change is that, for the most part, the starters and their subs are seeing about equal time. Rather than a situation where Tegray Scales played almost every possession and Raekwon Jones gave him only the occasional break, this year the top two linebackers at each spot are playing roughly a 60/40 or 50/50 snap split. The same is true for every position except field safety and husky, where Jonathan Crawford and Marcelino Ball still command the lion’s share of the PT.
- Along the defensive line, there’s a fairly well-established two-man rotation at each spot, except for nose tackle, where there’s a very large three-headed monster of Jamerez Bowen, Mike Barwick and Kayton Samuels. James Head made the briefest of appearances at WDE against UVA – seriously, it was two plays – which suggests that the coaching staff is not particularly concerned with conserving his redshirt year (i.e. they expect him to play more than 4 games). Otherwise, that’s a pretty large waste of one of his four games of participation.
- At strong or boundary safety, true freshman Devon Matthews regularly enters the game in passing situations. Otherwise, Khalil Bryant and Bryant Fitzgerald split the action.
First of all, how about Andre Brown?! I’ve been critical of Andre’s coverage skills over the past few years, but through two games in 2018, Brown’s man has been targeted five times, and Brown is yet to allow a completion. And perhaps more importantly, he has not been penalized. This defense needed a shutdown corner to emerge, and maybe, just maybe, Brown is that guy.
Speaking of penalties, the secondary has been penalized at an alarming rate. In 2016, IU’s secondary was whistled for just six pass interference or defensive holding penalties.1 In 2017, the secondary drew 15 such penalties. In 2018, IU is on pace for a whopping 36 defensive holding or PI penalties. A’Shon Riggins had a rough night against FIU, getting called for 3 penalties.2 Raheem Layne has only been called for one so far, but it was a big one, as his PI not only took away a game-sealing INT, it also gave UVA one more shot at the end zone.3 And true frosh Jaylin Williams has apparently decided to never allow his man to catch a ball, penalties be damned. He’s had the ball thrown his way twice, and he’s been called for a penalty each time.4
So two total pressures against FIU and a pressure rate of 9% isn’t great. In fact, that’s the lowest pressure rate since I started tracking it in 2016. The good news is that IU’s pressure rate ticked up to 26% against UVA, but that’s still below the 29% average that Coach Allen’s squad maintained in 2016 and 2017. It should also be noted that several of IU’s pressures against UVA were the result of Wahoo QB Bryce Perkins rolling out and drawing late pressure from a spying linebacker, rather than from pressure in the pocket. The man we expected to lead IU in pressures, WDE Nile Sykes, has yet to record one.
Other notable pass rush developments:
- In my two-plus seasons of tracking this, Coach Allen has never rushed seven. Until Saturday against UVA, when he brought seven in the 4th quarter. I suspect this was a reaction to UVA playing max protect and only sending three receivers out at certain times. I will be surprised if we see it going forward.
- In two years playing for Coach Allen, Jonathan Crawford has rarely been used as a blitzer – maybe 3 or 4 times in total. During the 4th quarter against UVA, Crawford blitzed twice, once from the field and once from the boundary. I will not be surprised if we see more of this going forward. This defense will need to be creative to generate sufficient pressure, and Crawford is a good athlete who should be able to get to the QB (although he didn’t in his two blitzes on Saturday).
Rushing Defense and Tackling
Against FIU, it is clear that IU’s relative struggle defending the run was not a tackling issue. In fact, only one of IU’s already-low total of four missed tackles came on a running play. The bigger problems seemed to be getting off blocks and keeping contain on bounce-outs.
On the contrary, IU’s front seven was more disruptive against UVA, while also maintaining their assignments. Tackling was a struggle, but I’m willing to chalk some of that up to the rain and to Bryce Perkins simply being difficult to bring down. Although you’d rather not have any missed tackles, it’s worth noting that several of IU’s missed tackles against UVA occurred in the backfield and contributed to the ultimate failure of the play. Although further improvement is needed, IU’s defense was better against the run – against an almost certainly better rushing team in UVA – in Week 2 than they were in Week 1.
One other note on missed tackles: Khalil Bryant had the key missed tackle on Perkins’ 47-yard scamper in UVA’s first drive. He missed another tackle later, and he got torched on a wheel route for a TD. But to Bryant’s immense credit, he continued to play the next play, and he made a huge open-field tackle on Perkins late in the game.
