"No distinct difference in the ability" between TJLQ, Sims, and Haarberg, if you completely ignore the fact that Sims turned the ball over at approximately 45x the clip that TJ does, and Haarberg probably 3x.
We absolutely need a portal QB but come on. He's not a good QB at this point by any stretch but you could make a much more convincing argument that he's the second best QB to take snaps under Rhule lol
These are the passing ratings for each Rhule QB's Nebraska career on sports-reference.com
Sims: 91.5
Haarberg: 105.0
Chubba: 111.7 (only counting his 2023 stats, not snaps under Frost)
TJ: 133.7
Dylan: 140.8 (158.6 in 2025)
