Davis was a super young kid from a state that is very poor for high school talent. He is absolutely still a prospect, as he is still nearly 2 years younger than average for the Midwest League. Is he still a longshot? Yes, but his strikeout rate is down, his walk rate is up, and his hitting is up in literally every aspect. His OBP and SLG are both up by literally 100 points from last season. That is called improvement.
People expect every kid to look like a top player right out of the gate. That isn't how it works all the time.
