I think Sarver selling raises the likelihood that the team moves but I don't think it's guaranteed. I know Grant Hill was involved with a group that was trying to buy a team not long ago, within the last year or two, and I can't see him being part of a group that would move the Suns. That would be if he was involved in a deal for who Sarver sold to.
Sarver gets a lot of blame, sometimes it's justified but lately I don't think the Sarver hate is that fair. He's been hands off and he stepped in because of how the team got embarrassed during it's opening this year. If what is reported is true about Watson telling players he had 2 weeks to win and lying to create an "Us vs Them" attitude regarding the players vs the management then he deserved to be fired, whether it was McD or Sarver doing the firing. When you're firing a coach so early in the season then I think it's normal to get approval from the owner. I've seen fans ripping him here, other message boards, and on Reddit though in addition to probably 3 articles about how he needs to sell the team from the national media.
When changes are made with a team, coaching or big time trades, you hardly hear other teams owners brought up unless it's a big market (LA with Buss or Balmer & NY with Dolan) or a famous owner like Dallas (Cuban) or Charlotte (Jordan). Somehow Sarver is mentioned just as much as those owners and he's not a celebrity and Phoenix isn't a huge market. Comparably how often do you hear the owner of Detroit, Orlando, Indiana, Philly, or Atlanta brought into discussions about their franchise? They're similar sized markets, so why does Sarver get singled out so often? I'm referring to the national coverage now. They're rarely mentioned unless the team is for sale, their owners aren't brought up during coaching changes or when their "star" player requests a trade. How often did the Pacers owner get mentioned when George asked out? I know Sarver made himself a target with his early antics, the chicken dance and the foam finger, but to still hold that against him when he's taken a back seat isn't fair, IMO. He has definitely taken a backseat, that isn't just spin either. Go to another teams message board and see how often their owner is mentioned, I guarantee it's less than Sarver is brought up by Suns fans unless it's LA, NY, Dallas, or Charlotte.
