Can fans petition to fire Steve Kerr?

I am not a Suns fan, but am a basketball fan. I think Kerr has done a terrible job since taking over. The suns went from a 60 win team to where they are now in about 2 years. To answer your question, the fans can start a petition if you get enough signatures. There are a lot of other ways you can protest, such as carrying signs outside/inside of games voicing your sentiment. You could boycott games, and merchandise. If you make your anger known in the right way, ownership will certainly listen because the fans are the ones who make the team's money. You guys pay, you definitely have a right to complain. If you get enough support (financially) from other fans, you can rent an electronic billboard in the city and voice your opinions there. The Buffalo Bills have done the same, as have other teams. Freedom of speech is a beautiful thing. Exercise your rights!
