Starting a hockey game means nothing. Is the kid the #1 D? Does he run PP1? Get all the important minutes? If so, who cares who is on the ice for the anthem?

I agree for the most part. Ice time and playing in key situations means much, much more than starting. Also, sometimes coaches try to match certain players, so starting sometimes depends on what the other team is doing.
