A lot of the run defense issues go back to the linebackers. Roberts was pulled in the 2nd quarter after being absent/ineffectual on a few big plays. Marquez came in and helped settle things down.
We spent the second half with: a true freshman low 3* (Maddox-Williams), a true sophomore 2* (Morris), and a 5th year former walk-on special teams player (and DE and FB) in just his second year at LB (Marquez). Honestly, they exceeded my expectations in the second half, limiting the big plays and keeping Minnesota out of the endzone.
Next year we get Manning (3* 5.6), Lumor (3* 5.6) and Battle (3* 5.5) off their redshirt year, and Fogg (4* 5.8), Fatukasi (3* 5.6), and Onyechi (3* 5.5) coming in as freshmen. Hopefully the increased competition will see an improvement at the position.
As far as the special teams... that can be a symptom of a lack of depth. When guys who would ordinarily be backups are starting... there is less in the cupboard for kickoff and punt coverage teams. We're using some starters on those teams, too, but with the lack of depth we have, you have to try to limit the risk of losing guys to injury, too. I'm expecting this to improve in the coming years.
