stop shifting the goalpost and answer the questions.
your 4 questions are so ridiculous but I will answer anyway:
Go ahead and explain why you think team's record is the best way to evaluate coaches' competences?
Because to evaluate a coache's competences, you need this:
-following the team (knowing what's happening within the team)
-knowing the players
-knowing what coaching a hockey team is
-and so many other factors that fans doesn't have at their disposals.
Is putting the 3 best coaches in the NHL behind the Coyotes bench will make them successful?
No coach can make the Coyotes make the playoffs, their roster are too poor.
How much of the record is directly attributable to the coach's abilities?
A lot of the record is attributable to the coaching staff abilities, and we've seen so many exemples over the years. Look at Bob Hartley success over many years, many differents leagues, many different teams. Not just Hartley, there's a lot more coaches that had success over different teams or/and leagues or/and eras like Scotty Bowman
If the team/player are not that good, as you said earlier, how does Michel Therrien manage to make them win? Sheer force of will?
There's no sheer force of will, there's teaching, there's managing, there's planning, ect, etc and we as fans have no clue what's happening behind closed doors, we don't know what the coaching staff are doing.
And the sick thing is even if we knew what would be happening, we wouldn't know if it's good or bad because we're not qualified.
The only way we can judge, is by looking at the record.
