With soooooo many roster changes by sooo many playoff teams, there is no way to come close to the correct answer.
The success of any team depends in large part to how well the role players complement their 2 best players.
Results from last season would indicate Dame/CJ were the second best in the west, since they made it to the WCF.
Maybe we should have some fun by watching the games and see how the question plays out. Trying to find the answer in stats is like trying to find an honest politician that does not lie.
