Depends on what you mean. Bryce and Alontae aren’t better than they were as freshmen, but they are better than what we had in 2017.
LB, despite Tootoo being extremely good, is overall maybe worse than when Pruitt started.
WR is clearly worse. Tight end is worse.
RB isn’t better. QB isn’t better. Safeties aren’t really any better.
OL is probably better, but not nearly where it should be and still not close to living up to expectations based on recruiting.
DL is probably the unit he has improved the most, but I’m not sure how much credit to give him. He fired the guy that really oversaw the improvement, looked at one replacement candidate, hired him without an interview, made him co-DC and overpaid, and finally fired him after four (or perhaps less) games.
