Nowhere in the thread have I said "how a team celebrates wins, in and of itself, causes subsequent winning or losing."
Direct quotes:
The nature of the locker room celebration itself isn't a causative factor in anything. It's the team culture it reflects that's causative in winning and losing. Locker room celebrations in themselves don't cause winning and losing -- team cultures do, however. These locker room celebrations are simply reflections of their teams' cultures.
The problem is that the 2025 Miami Dolphins' "personality" isn't consistent with winning at a high level in the NFL, where seriousness, drive, determination, and aggression are what wins on the field in the rough and tumble game of football.
So we can tell their "personality" by
how they celebrate wins, and their
personality "isn't consistent with winning."
You are drawing a direct line between celebrations and culture, and an equally direct line between culture and winning.
To say "A = B" and "B = C" is to say "A = C."
Moreover, the Rams are 8-2. The Dolphins in the video in the original post were 3-7. Even if there were some silliness going on in the locker room on the Rams' part, it would've been occurring in a completely different context in terms of how the team has performed overall. There should be no such silliness on the part of a team at 3-7 that should be functioning with dead set seriousness on turning its season around. Silliness in that context is an indication of team culture dysfunction.
And finally, we arrive at "Scoreboard."
This would all be a lot easier if you just said "Winning teams are good and smart, while losing teams are bad and dumb." And that's a completely defensible take! It's childishly obvious and simplistic, but
at least it's an ethos. However, a take like this rings somewhat hollow if you disappear when this logic can be used against you; to take a random example, if there were a coach that you criticized as being "unserious" who was sitting at 9-3 in the #1 seed entering week 14.
