You would have to show me some evidence of how responsible Cotton was for that.
Otherwise, I'm not willing to make assumptions. How would I know that some of those Suns players didn't just quit on Cotton like DeAndre Ayton quit on everyone? If they did and I blamed Cotton, then I should also blame Monty Williams for Ayton quitting.
(And that means
everyone. Ayton also quit on the fans, and wasted the playoff ticketholders' money.)
I was just looking up that Suns-Kings series, mainly because the year wasn't mentioned and I wanted to know. I should share what I found:

It sounds pretty darn embarrassing, because it states that half the Kings team was injured. At least
these Suns didn't get beaten by a half-strength team with a 40-42 record. It made me wonder whether some of the Suns players were already using drugs; but nah, they probably didn't start years before the scandal. Probably.
