Outside of the Oregon football game, I am pretty much in the camp of those that believe it is never the officials fault that you lose. With that said the Football team was cheated by the Pac 12 Officials on the field and Gordon Reese in the replay booth.
There's a difference between claiming it's the officials' fault your team lost and merely acknowledging that the officiating was a negative factor in the game, an obstacle to be overcome. The former absolves the losing team of its role in losing the game, which I agree is almost never justified; the latter merely acknowledges that bad officiating can sometimes play a role in the way a game plays out.
In basketball, it is sheer denial to pretend that officiating, which varies greatly from official to official, crew to crew, game to game and even stretch to stretch in individual games, never unduly impacts a game.
And generally those who like to pretend that officiating doesn't play a role seem to take a special pride in puffing out their chests and calling out those fans who might cite the poor officiating. It seems to make them feel like tough guys, I guess, to blame the players and/or coaches rather than the officials. Often, though, there's plenty of blame to go around and the officials fully deserve to come in for their share of it.
That was certainly the case in the Creighton game, in my opinion.
All that said, if I were a coach, I'd rarely, if ever, mention the officiating to my players (or the press) because there's little to be gained from it. The players should focus on what they need to do to improve and the press will just paint the coach as a cry-baby.
But I don't believe for a second that most, if not all, coaches, don't at least occasionally bemoan in private the one-sided officiating they were saddled with in a loss (or acknowledge, when it applies, that they got a break from the officials on a given night).
