Why is Don Cherry going to stay on HNIC? Because the mere mention of his name, and even just guessing if he'll still be on or not--will lead to a thread with tons of posts. Love him or hate him-you'll be talking about him (and watching). And that's what they care about.
Don Cherry is not very nice person concerning foreign cultures and customs. But he is having work in Canadian television station, so why should he have concern over other people than Canadians? I never see Don Cherry and I don't think many people do either.
