For Michigan State to rebound from 2016, its defense will have to make drastic improvements in 2017. Across the board, the Spartans struggled defensively on the way to a 3-9 record. MSU’s lack of pass rush contributed to the ineffectiveness of a vulnerable secondary, and vice versa. Meanwhile, Michigan State got some solid linebacker play, but it was inconsistent because of injuries and general up-and-down performance.
