It's a useful tool for team motivation, but I think most people realise that these meetings matter more to the storytelling afterwards than the immediate.
"Lads, let's choose to win basketball games instead of losing them".
"Yes".
And win the team did.
Compared to: "We said we wanted to win more games, but we lost them instead, and it turns out we're really just not good".
Clearly the Kings, Magic, insert perennial under-performer here have these meetings as well. No one cares because they don't measure up on the talent scale.
