With all 3 starters from last year gone, the Hoos have almost no returning experience at LB. New MLB Micah Kiser has played a few plays at the position, but the projected starting OLBs have seen action almost exclusively on special teams. Coaching them up and getting them to a point where they can be productive is going to determine how well this defense plays this year.
A year ago, the Hoos trio of starting LBs finished 3, 4, 5 on the team in tackles with 217 total stops. They also finished 1, 2 and 5 in sacks with 19 total sacks.
