I tend to agree with that you're saying but the fact of the matter is most of what you said albeit insightful doesn't matter. At the end of the day, they didn't like him. As you said, he wasn't getting along with some of his players or the GM. The HC is the bridge between the two and very important. If he wasn't right for the culture, it may not even matter if he was winning because a terrible culture will always crumble and it does not take long. He just isn't there guy. Doesn't mean in any way he's not the perfect guy for someone else. There are far worse.
have we seen any evidence that he didnt get along with the players?
so far all ive seen is players disappointed that he's been fired...
and while you can point to the disappointing record, it completely ignores the historic turnaround - no team has ever lost 7 straight and then won 7 straight - obviously the first half of that stat is bad but the 2nd half is unprecedented - you can argue they didnt have any impressive wins but the play level was higher, the manner in which they did it was effective and clearly the players believed in him and fought for him
the front office and owner can ultimately do what they want but idk that i wouldnt be somewhat disillusioned with the front office as a player right now (especially given that it's the front office who's created all the speculation about Tua and not flores)
