There is no "perfect" personality for a head coach. Watch pro-sports long enough and you will see lots of quiet coaches, loud coaches, in your face coaches, "player" coaches, demanding coaches, amiable coaches and old-school never smile coaches; and you will see some in all categories be successful and some in all categories who will fail.
The best coaches are the ones who, regardless of personality, establish an urgency in how their team approaches their business. Not panic, not being on edge, not worried...just calm urgency. Every game, every period, every shift, every puck battle matters and everyone knows it.
Would anyone describe Housley this way? It's not a put-down. It takes off the charts leadership ability to be a consistently successful head coach in professional sports.
