Cam Payne reviving his career as a good backup guard started in the bubble. Cam Johnson establishing himself as a quality sf/pf who can defend started in the bubble. Dario Saric changing his role to a center and leading the bench started in the bubble. Mikal Bridges taking his defense to another level started in the bubble. It wasn't a fluke, it was all real, and it carried over into this year.
The bubble Suns were not a Cinderella story. It was a young talented team with a new coach evolving to the next level. I'm telling you as a Suns fan, Monty changed the culture. Look at Rubio on the Suns compared to Rubio on the Wolves. Look at Oubre on the Suns compared to Oubre with the Warriors. Monty's culture and system makes players better.
The Suns would have been a playoff team(6-8th seed) this year even without CP3 but I do give credit to CP3 for pushing them to a top seed in the west.
