I think the Jazz will overachieve simply because the expectations are low around the league about the Jazz. Everyone does need to remember that other teams have improved. They will be improved but the real key is if the Jazz buy into improving their defense. Jazz has plenty of guys who can score especially in a team system, but you have to make stops in order to win in the NBA.
Jazz have been horrible on defense, but they have some guys who have great potential, Kessler, ACE, Henderson and C. Williams all have the length and athleticism to be above average defenders. Experience, effort and injuries have been obstacles for them to overcome. I think the Jazz will be better than most people think but the results might not be much better because the West is stacked with good teams. I am excited about this team and who is going to step up when given the chance.
