Position that needs improvement: Indiana

All week, we've been examining a problematic position for each Big Ten team during the 2014 season and how it could potentially be repaired in 2015.

Last but not least: Indiana Hoosiers

Problem position: The secondary

Why the secondary was a problem in 2014: Honestly, we could have picked the entire defense as a problem spot for the Hoosiers. Again. Despite the hiring of a new defensive coordinator (Brian Knorr) and an infusion of more athletes on that side of the ball, Indiana once again struggled to stop anybody in the Big Ten. Knorr's unit gave up more passing yards per game (250) than anybody else in the conference, and opposing Big Ten quarterbacks completed 63.9 percent against the Hoosiers. That's an indictment on the lack of a pass rush up front and linebackers who can cover in space as well, but we'll focus on the defensive backs for these purposes.

How it can be fixed (solutions on the roster): Safety Mark Murphy and cornerback Tim Bennett, two of the leaders of the defense, used up their eligibility. Meanwhile, the team's other starting cornerback, Michael Hunter, decided not to return for his final year. That leaves the Hoosiers thin on experience going into 2015. Safety Antonio Allen, who was an important recruit for the Hoosiers, needs to continue to improve as a junior, and Chase Dutra likely joins him as a starter. Cornerbacks Rashard Fant and Donovan Clark saw action last fall as freshmen, and Kenny Mullen returns from an injury.

How it can be fixed (potential help from 2015 recruiting class): The Hoosiers have a pair of safeties -- Jonathan Crawford and Tyler Green -- ready to sign next week, as well as several athlete types who could play either linebacker or defensive back. They could still be in the market for a late addition at corner.

Early 2015 outlook: There is talent on hand here. Allen and Fant, for example, are two of the top-rated recruits Kevin Wilson has signed. The defensive backfield roles are actually more settled than wide receiver, which is a worrisome area on the offense. Again, the secondary was by no means the only weak link in the defense. But until Indiana can figure out a way to strengthen every aspect of the defense and become competitive on that side of the ball in the Big Ten, we could be talking about the same problematic positions for the Hoosiers in 2015.
