Losing culture gets misconstrued as some kind of all-encompassing funk that hangs over a team. What it really means is that a team just consistently fails to get the right mixture of talent, attitude, chemistry, work ethic, and leadership qualities. A losing culture can be a team with too much talent and no work ethic. A losing culture can be a team with a ton of work ethic and no talent. Or a ton of talent and no chemistry. A winning culture is just a team that has managed to hit on the right mixture for an extended period of time. Perhaps there are some talented scouts or a talented GM or coach who has a good read for what guys bring what to that mixture. You see winning cultures on teams like Boston where a group of guys really just works well together in the room (Marchand, Bergeron, Chara), and they hold things together through coaching and GM changes and roster turnover. They might turn into a total dumpster fire of a team when those guys retire. Who knows.
