The consensus is that defense should be the strength of this Indiana team in 2022. There is good reason to believe that the Hoosier Defensive Coaching Staff led by Tom Allen can have good success this season. As most will know CTA (the 2020 AFCA National Coach of the Year) is a defensive guy and had a good track record for solid / disruptive defenses prior to arriving at Indiana in 2016. The Hoosiers fielded one of the nation's most improved defenses that 2016 season. In fact, from the beginning of 2016 to the end of 2017 Indiana was the most improved team nationally in terms of total defense and pass defense. Before last season's rather unexpected 2-10 result Indiana was 24-21 overall in CTA's first three full seasons (excluding the Foster Farm's Bowl in 2016), including the 14-7 stretch from 2019 to 2020. Indiana was nationally ranked during both of those seasons and as high as 7th in 2020. The Hoosiers appeared in the Gator and Outback Bowls respectively during that period.
The lazy take is to say that 2021 marked a 'return to normal' for this Indiana program but the truth is that going all the way back to arguably 2013 IU had been performing at a consistently higher level. It is not being a homer to say that until proven otherwise the aberration was 2021, not the longer period of increased success. Keep in mind that in both 2017 and 2018 Indiana went into the Bucket Game a win away from Bowl Eligibility before ultimately ending up 5-7. (Zach Osterman did a good job of expanding on this on Crimson Cast last week.)
Allen gave up calling defensive plays in 2019 so that he could devote more time to overseeing the entire football operation but will return to calling the shots this season. Allen's defensive scheme is solid. I am somewhat flexible on scheme as long as it is coached well and players buy into it. That said I do believe Allen's scheme to be an exceedingly good one. The hybrid Bull and Husky positions are a needed response to modern offenses and allow gifted players to serve multiple purposes as needed without having to change personnel packages.
Hoosier Huddle reported in a recent podcasts that Indiana is returning to the vision zone concept on defense. (I'm fairly certain he was referring to vision match.) I first heard about this concept while watching a 2019 Ohio State game called by Kirk Herbstreit.
The popular approach to zone coverage in football has long been zone match, which merges zone principles and man to man techniques. In zone match players are taught to 'break on the ball' and defenders' backs are often turned away from the quarterback / ball. The problem with this is that quarterbacks have gotten so polished and routes so precisely timed that a potent offense will pick these conventional zones apart and beat them more often than not. (Good offense beats good defense.)
The idea behind vision-match is to keep everything in front of you, have your eyes on the quarterback at all times and react according to the QB's eyes. (This actually ties into the don't think just react concept I saw a couple people discussing elsewhere on this forum.) The strength of this system is that it limits explosive plays when executed properly. As far as offenses are concerned explosive plays are the name of the game right now.
I actually brought this specific concept up with Kane Wommack on Twitter in the Summer of 2020, though at the time I didn't know the proper terminology. To my surprise Wommack not only responded but seemed excited to talk about it. I remember he also mentioned not covering the route tree alone but being more efficient by covering where the ball was most likely to go. The point to all of this is that Herbstreit (rightly) predicted that this vision match concept would be the direction a lot of defenses would be going. Evidently Allen and Wommack were on top of it.
This is a long-winded way of demonstrating that the IU defense is ahead of the curve and in good hands. I did some digging this afternoon and by my count Indiana's Defensive Staff have coached in a combined 58 Bowl Games.

Defensive Coordinator / LB - Chad Wilt
Defensive Line - Paul Randolph

Chad Wilt is a coaches kid who considers himself to be a teacher. Wilt's previous three stops before Indiana were Minnesota (20-21), Cincinnati (19) and Army (16-18). During these three stints Wilt's teams went a combined 52-21. The 2019 Cincinnati Bearcats finished the season ranked 21st in the AP Poll.
Paul Randolph comes to Bloomington by way of Texas Tech. Randolph has coached in 17 career Bowl Games and has previously coached at Memphis, Arizona State, Pittsburgh, Rice, Alabama, and West Virginia.
Brandon Shelby enters his 12th season with Indiana and has coached the likes of All-American Tiawan Mullen and two-time All-Conference Rashard Fant. Shelby also played at Oklahoma.
Jason Jones begins his 3rd season at IU. His recent pupil Jamar Johnson was First Team All-Big Ten in 2020 and was drafted by the Denver Broncos (5th Round) in the 2021 NFL Draft. Jones has coached on 5 conference championship teams and in 14 Bowl Games, including 2 New Year's Six games and a Fiesta Bowl championship.
