Though experiment:
How many Chris Pauls can you insert into the lineup before the overall defense suffers and why?
If you have three Chris Pauls, then you would need two elite defensive players at the remaining two positions.
If you have two Chris Pauls, then you would need one elite defensive player, one above average defensive (compared to the top 20% of the league), and one average player.
The Jazz are a team with two "Chris Pauls", an elite defensive player in Rudy, and then other two spots we are average (compared to the top 20% of the league because that is who we are fighting for the championship). The Jazz need to upgrade one more spot defensively or we are going to be average defensively. Defense is a team construction/unity concept and the Jazz are at a disadvantage.
