Fact is, we can only judge results, not nit pick each decision, a team is a holistic entity, and there are reasons for decisions that are not disclosed to well after the fact.
Y'all can pontificate about what you would do as hockey geniuses, but that doesn't mean I have to accept your self assessment of your superior judgment.
The better player is not the most talented player, it's the player in that situation, taking into account both short-term (this game), medium term (this season) and long term (player development), as well as externalities as team chemistry, personalities, etc.
Like I said, most of the complaints here come off to me as whining about trivial decisions that had little impact on winning and losing.
Sanheim being the perfect example, in hindsight he had no impact on the team at the beginning of the season, either when he played or when he was demoted, and only a marginal impact when he returned. So we'll see how he develops, but as far as last season, pretty much a non-issue.
In the end, a coach is judged by how his term performs relative to its talent, last year's team had mediocre talent, certainly far less than Toronto, so does that make Bowman a bad coach?
