Torts was fine (but limited, and I think everyone is of the opinion that Torts goes so far and runs out of steam) and I liked Renney.
What do I like about Gallant? He wins. He wins games consistently enough that it's not a coincidence. I think he probably deserves some nod for Kreider producing his best offensive seasons even as his physical skills are aging away. Our analytics are better, you know I like that.
I wouldn't say I dislike every Rangers coach. It's more so that I dislike hockey coaching. I feel that while other sports have innovated, hockey still has a lot of the same old tropes.
For example, every coach is going to have a toy (or two or three) that he plays way too much or way too high in the lineup because (you're not gonna like this) they think bad players are doing "stuff" like "creating space" or "being responsible" or whatever other tropes. There are ways to measure this and most of these players are doing nothing. Hockey has that "grinder" culture that other sports don't have; a penchant for players who work hard because they have to, because they're not good enough. Granted, the NBA has what you would call "glue guys" but they tend to be good at tangible things like rebounding and defense. Most coaches' toys around the league just suck.
Maybe hockey is just unique in having this type of player, or maybe it's just primitive thinking. You could argue either way. I certainly think it's the latter.
I don't think things I disagree with are right just because every coach does them. That's appeal to authority, simple as that. I also have an understanding that every coach is going to do the things Gallant does that most people complain about and I don't blame Gallant for the lack of development. There's plenty of other schmucks around the league saying "I like my lineup" while the house burns down and the cat runs away, and those organizations' young players are fine.
