I don't hate Hiller, he probably is the most likeable coach the Kings have had, but that also is possibly a con all on its own. I sort of like that he is forthright with his opinions and blunt about his assessments. He has convictions about his decisions, argues them well, and makes some good decisions that does deserve some credit for getting home ice advantage in the regular season.
However, in the end, he just makes very questionable decisions in the most clutch situations and dangerously mismanages his bench. His reliance on vets while double-shifting them endlessly until they can't even move anymore and then hiding his roster depth, which was one of the team's biggest strengths heading into the postseason, is mind-boggling. He's not the worst coach the Kings have ever had, and while I was against his hiring he did do some things and performed a little better than I had expected in the regular season while somehow being worse than I thought he could be in the postseason.
Unfortunately, he's gotta go with BLuc and the house needs to be completely cleaned. Fans have no say, so they aren't going to green light another rebuild, but they had to at least consider a heavy retooling. Kopitar needs to be on the third line with limited to no special teams, and Drew has to be on the 2nd pairing or less with maybe 2nd unit special teams capacity with restricted minutes. Byfield and Clarke need to be given a long leash and they gotta make some tough choices about their vets and possibly move some for younger players/assets.
