People ask was it a mistake trading for Shaq? are there too many new pieces? why is the cavs offense not as good as good as last years? I think the reason is the loss of assistant coach John Kuester who was the offensive genius for the cavs. The cavs before John Kuester was the 19th ranked offense and when John Kuester joined the staff the cavs went from 19th to the 4th ranked offense and in that same year they won 66 games, Mike Brown was named coach of the year, and Lebron James ended up winning the MVP award. Now I'm not saying that it was all John Kuester but you have to think he had to be a major contributer on the sidelines.
