back in the day when there were wars against western nations, the defeated nation would typically head home with their tail between their legs and everyone would blame the leadership for the poor performance. It was easier to imagine that their soldiers (typically theirs sons etc) were just as good as those fuging prussian pigs, or those papist french, or the godless british sailors, or whatever; they just had a few jews or whatever that had snuck into the upper echelons and fuged it up.
better leaders and we're just as good as the rest of them! next war!
well, sometimes the soldiers just aren't that good. italian soldiers weren't defeated by ethiopia because of bad leadership. the americans didn't get routed by canada because they didn't have good generals. sometimes your soldiers just fuging blow....
....even your favorite one.
It's easy as fans to pin everything on the coaching staff, because it's easier to fire 10 dudes than replace 30.
It's easy to blame the lack of development and, dare I say regression, of a certain favorite player, on the bad coaching, other elements, weather, commercial shooting schedule, etc.
sometimes the british send a bunch of inbred australians over the barricades into machine gun fire. sometimes the soldiers just can't cut it against starving koreans/vietnamese.
