SAN FRANCISCO -- It's not often that a team owner publicly calls out a pocket of his own fan base.But, in my opinion, San Francisco 49ers CEO Jed York was within his right Sunday when he went to Twitter to express his disappointment that some fans did the wave late in a 32-20 win over Arizona when Cardinals star defensive lineman Calais Campbell was being taken off the field on a stretcher.York tweeted that it would be an "understatement" to say he was disappointed to witness the act.
