I don't recall any member here saying that crunch time scoring problems were "easily correctable." They were merely asking for the coach to exercise some coaching acumen and try to use his position to give his team the best chance in crunch time. It's always tougher to score late in a close game...NBA fact of life.
But the one point we all seem to agree upon is that this end game "behavior" is not optimal.
One camp says... oh well, it's going to happen, always has, always will, happens to all coaches/teams, good and bad, cohesive and non-cohesive, so you just have to live with it.
Another camp says, why should a coach sit back and accept it, when the coach has some possible control of the team's performance in the half court (and thus the game's outcome) by calling a set play, asking for more ball movement before a shot, or the like when his team shows a trend for poor, ill-timed, forced shot selection in crunch time?
Folks understand that every possession will not be a good one, there's the matter of that OTHER team out there trying to stop you and disrupt you, and players just plain don't always do what they are supposed to do (ie, play smart ball).
Nevertheless, as a fan, asking for some order when there is late game chaos in a close match is by no means being out of touch with reality, or failing to understand the game, or being "ignorant" as some in their condescension would try to have you believe. Just as a coach calls a timeout to stop a team's run during the course of a contest, so should he also exercise some control at the end to get his team to play, what we all agree is, optimally.
