Why does everyone think Rose is way more valuable to the Bulls than Deng or Noah?

If Rose was the Bulls only good player, they would not be the #1 seed. But Rose is still by far their most valuable player. Without Deng this year, the Bulls would have still been a top 4 seed. They finished 10 games ahead of the #4 seed, and Deng doesn't make a 10 game impact. Without Rose, they would have been a 7th or 8th seed.
