Yes, I believe Castle will be at least an average offensive player. When I look at his shot, I don't think it's broken, and I think he has a chance to be a good/great offensive player as well. Even if he's just ok then he can still fit in as a 5th starter and play an important role on the team. I think it's far less likely that Brice becomes an effective starter quality player in the league for the reasons in my other post.
I disagreed then, and disagree now with the Jazz's priority of drafting shooters vs getting all around players. We are currently one of the worst defensive teams in the NBA. We currently don't have the players to put together competent defensive lineups.
