I watched the first half of this game and highlights
Rutgers was mostly a single back, 11 personnel unit. Mixing in 12 personnel near the goal line. Run heavy for the most part, when they did throw, they typically threw deep and away from underneath coverage.
3-4 base, with a designated Rush end to make it behave a bit more like an Under front than a true 3-4. Lots of twists and slants to get the DL in one-gap situations. Mostly zone behind.
