Neurosurgeon: Don Cherry is Hurting Hockey: CBC television commentator Don Cherry has become a negative influence on the sport of hockey by promoting violence, a neurosurgeon claimed in today's Toronto Star. "We've been too gentle with him over the years. We've allowed him to change the culture of hockey," said Dr. Charles Tator, who claims he sees hockey players as patients every week. "One mother this week told me that she felt that because her son is such a talented player, there is a bounty on his head. We have to get rid of head-hunting."
