He might not be as non-committal to ownership and Wings staff, players, etc. He just doesn't share his plans publicly other than to give broad, generalizations "We want to win" "Please be patient" "We want to build for the long-term", etc. etc.
For all we know, he has daily meetings with ownership to go over a detailed roadmap of every iota of information and step, etc. (I doubt it, but more to make a point).
Yzerman doesn't share anything - thats just his style? Just because they are unknown to us, doesn't mean they are unknown to them.
