This week in Defensive Film Study: some talk about the challenges ahead, but mostly just CHARTSSSS.
- Ralph Green’s return from suspension pushed Patrick Dougherty into a smaller role at DT. Ralph Green was easily IU’s most impactful D-lineman against Ball State and barring significant development from any of the defensive ends, should carry that mantle for the rest of the season. Because Green and Dougherty were both available at DT, Jacob Robinson did not slide down to DT, as he did occasionally against FIU.
- Nate Hoff played about half the time at NT, with Mike Barwick and Ja’merez Bowen splitting the other snaps.
- At safety, Chase Dutra’s return from suspension pushed Jameel Cook out of the rotation at boundary safety. Tony Fields remained the starter. At free safety, I don’t have an exact count, but I believe Jonathan Crawford played more non-garbage time snaps than any other IU defender. Khalil Bryant briefly relieved him for part of one series.
- At Husky, Marcelino Ball and Zeke Walker had about a 70/30 snap split. While Ball’s positive contributions have been well-documented, Walker also looked good in this one. I wonder if we’ll ever see them on the field at the same time in passing situations.
- The linebacker substitution pattern was similar to what we saw against FIU. Dameon Willis continues to see significant playing time in relief of Marcus Oliver, particularly on passing downs.
- At corner, all but a handful of the non-garbage time snaps were manned by some combination of Rashard Fant, Ben Bach and A’Shon Riggins. Walk-on Arthur Jones also played a series at BCB.
Nothing To See Here, Move It Along
Through two games, one quarter of which was garbage time, we really do not know much about IU’s defense. FIU’s and Ball State’s offenses are both outside the top 100 now in S&P+[ref] 116th and 102nd, respectively.[/ref] and appear likely to remain in roughly that area throughout the season. Suffice to say, this defense hasn’t been tested. Largely because his defense has not been tested, Tom Allen has utilized fairly straightforward blitzes and coverages.
Based on the little we’ve seen, one might conclude that this defense will make more plays than the 2015 version, but the 2015 version actually created a few turnovers in non-conference games as well (and then the rest of the season happened). If last year taught us anything, it’s that we should be careful about drawing too many conclusions from the first few contests.
Challenges are coming. This week, Wake Forest’s run game will be the best offensive component (rushing or passing) that IU has faced this season. That isn’t to say that Wake, especially without their best running QB and top running back, are a particularly strong running team, but at the very least, they appear competent.[ref]The Demon Deacons are 39th in rushing success rate.[/ref] On the bright side, the IU defense can overplay the run because Wake really struggles to pass.[ref]110th in passing success rate.[/ref] After Wake, the first three weeks of October feature three challenging offenses – Michigan State’s power running game, Ohio State’s crazy talented offensive juggernaut and Nebraska’s strong passing attack. We will learn much more about this defense and Tom Allen’s schematic prowess in those games.
For now, take a look at the usual charts. We’ll dig into analysis once IU is challenged and shows its defensive hand a little more.
CHARTSSSS[ref] Like yesterday, all the numbers in the charts are limited to non-garbage time, meaning they exclude the entire 2nd half except for Ball State’s last series when they were down 10 with less than a minute to play.[/ref]
Takeaway: Riley Neal struggled, but IU did a decent job of tackling on short throws in front of them, limiting 6 short completions to a reasonable 62 yards.
Takeaway: Ball State was terrified of the right side of IU’s defensive line…or that was a fluke. The Cardinals found a little more running room than you would like to their right, defensive left, averaging over 6 yards per carry in that direction.
Takeaway: Heavy use of the 5-man rush. IU used a 3-man rush for the first time this season on the last play of the game.[ref] Which was technically not garbage time, but the game was over.[/ref] Still no 6-man blitzes yet.
Takeaway: Tegray Scales at WLB remains the most frequently used blitzer. One small change: both corner blitzes involved a defensive lineman dropping into coverage and the WLB blitzing as well, while last week, the corner blitz came with all four defensive lineman rushing.
Takeaway: Welcome back, Big Ralph! And IU needs more pass rush from its defensive ends.
Takeaway: IU blitzed (brought more than 4 rushers) on 9 of 18 dropbacks. The Hoosiers generated pressure, in the form of a hurry, knockdown or sack, on 6 of 18 dropbacks.
Takeaway: Chase Dutra missed at least one other tackle during garbage time. He looked a little rusty in this one.
