Head-scratching play calling on stalled drives (abandoning what is working and getting cute/trying to force something that isn't working)
Jaren Hall's ability to progress through his reads. After watching Zach play, I notice how much better Zach was pre-snap knowing where to throw the ball to. And Jaren struggles with inside crossing routes.
These things can be improved and once they are, this team will look really good. Beating 3 P5 teams (two ranked at the time of play) is already impressive.
