When the culture is bad, it's pretty obvious. Players X and Y always show up hungover and don't try their best, and other players let their dislike of each other interfere on the ice etc.
If things like this aren't happening, well, no matter how bad your team is, you have a room of guys who worked so hard as to be in the 1% of the 1% of the 1% of the population good enough to be there. If there's enough talent in the room conducive to winning games, if your team is built with the right stylistic brands of hockey players and has a coach that can bring them all together, then you have the culture, as long as you don't have the first thing I mentioned, and that's what Chainshot means from what I can tell. ie, you can't tell that this group of players (select any number of them, the ones who can actually play) can't be a part of a winning Buffalo Sabres team before trying it and getting these other parameters right, and so it's a waste of time to move them out for the sake of moving them out barring something egregious like mentioned above when everything else is still such shit.
