Bad call is made people need to move on.
Yes - and sometimes it is difficult for the team to do that after a bad call (or two) go against them, just as it's difficult to move on after two mental error turnovers in a row, or two crucial tough shots by an opponent, or whatever. Bad calls are part of the game - and impact the game in a lot of ways. Just like one play can be the turning point in a game (or a cluster of 2-3 plays in a row), so too can one call or cluster of calls. Waiving off a basket inappropriately, or granting two free throws inappropriately, or calling a third foul, or whatever... all have impact on the flow of the game, and not all can be as easily absorbed.
Usually better teams have more room for error, so a few bad calls aren't as impactful - teams that need things to "break the right way" to win get hurt more by a few bad calls in the wrong spots.
Officiating at this level is VERY difficult. Fans need to cut these guys some slack.
Agree - but so is playing at this level, and coaching at this level, and we talk at length about the relative positive/negative performance of the coaches and players after every game. There's really nothing different about saying "Johnson needs to hit more of his FTs" or "Sanders needs to work on going left" or "Omoruyi needs to hit those chippies" and saying "that ref needs to call that moving screen" or "that ref was wrong in waiving that basket" or "that ref was wrong in not calling that travel".
It's all discussing performance from tip to final buzzer - whether it's our own team and coaches, the opponent's team and coaches, or the three officials. And calls for an official's head aren't much different from calls for a player to be benched after a bad stretch - but there's no "officials coach" who can substitute for a referee if he "doesn't have it tonight", so even a ref in a "slump" has to get out there and do his best.
And TV gives the viewer the benefit of multiple angles, infinite replays, slow motion, focusing on different areas/players on each replay, infinite amount of time to make a decision, etc - while refs have to do all of that in one moment, live. So those with the benefit of all that technology have a bit of a leg up - which is why they institute replay for certain situations to get the calls right.
That can give fans more of a warped sense of *how* bad a call was, since it was so "obvious" on replay - but it may not have been obvious in real time from that ref's vantage point. Still, though, even if they're doing their best, that doesn't mean their performance on that night didn't impact the outcome in some way. So, "cut them some slack," yes.... ignore their impact on the game, no.
