The Indiana Hoosier defensive line will look immensely different in 2016 than it did at the end of 2015. Gone are the likes of Nick Mangieri, Darius Latham, Adarius Rayner, and Zack Shaw. Those four players combined to play in 50 games and make 153 tackles, including 17.5 sacks and 36 tackles for loss. Their production will be missed upfront and the Hoosiers will look for answers from some old friends and new faces. 
Indiana also sports a new(ish) defensive line coach in Mark Hagen, who replaces Larry McDaniel. The Hoosiers also add a new defensive coordinator, Tom Allen, who will try to implement a new defensive scheme— his 4-2-5 defense. This means the emergence of the new “Bull” position, which will be like a Bandit, but more of a true defensive end.
While the issue that stood out the most with the Hoosiers in 2015 was on the back end of the defense, the defensive line has to create some havoc in the offensive backfield. A good pass rush will help the still young secondary out by forcing throws a little quicker.
