He was okay the 2nd half. His season ended pretty miserably, though, where he fumbled 2 or 3 times against Ohio State along with throwing a pick 6. He threw for no scores. The guy finished with 22 turnovers which is insanely high.
He has a lot of tools that make you think he can be good, so his ceiling is high, but sometimes you have to look at a player for what they are now and right now he's nothing special, a turnover machine, and a guy that really will need a lot of hard work and great coaching to become good. I hope he can turn it around, but history says a guy like Darnold will not become anything more than he has shown to this point.
