Again, the point is that if you're looking to build up confidence in a young guy, you can still say many things without calling white black. Saying BS that's just not true has no upside and does no one any good.
You guys are still talking as if you are the intended audience of a coach's every comment to the media. You're not.
Is there a coach out there in any sport that gives reliable, honest, and critical analysis in every post game presser?
If you're implying that the comments were meant for Murillo, Armas could always mention hustle/reading the play/staying aware etc. Instead of making a point, he set himself up to be ridiculed and have his comments ignored.
I don't usually pay attention to public statements of coaches/GMs for precisely the reason you said (they're often just cliched and meaningless), but this one stood out for its disconnect to reality.
