can't speak for all.
but apparently during his time as a Canuck, he randomly takes out his anger on innocent players, for example screaming at David Booth for being late, when he was not late. He did things to really piss fans off such as benching Luongo for one bad game, so he starts Eddie Lack whois just a back up, so essentially forced a Luongo trade, he also never ran did anything with the power play. Also the way he plays, he did it diliberally to harm the Sedins, such as making them play a grinding style rather than allowing them to play their way which is effective as hell. Essentialy it felt like he coached to get his ass fired on purpose just so he can collect a pay check while being "fired" It felt like he wanted to sabotage the relation with Luongo and the Sedins.
thats just me.
He also didn't even bother getting a place here. He had a place at point roberts, and sometimes he will just stay over at a office at rogers Arena if he was too lazy to get back to Point roberts. I'm not f in kidding. So maybe he didn't like Canada to begin with? Which is also fine, but than don't except the job offer if he was going to coach half assed.
