Coronel was responding to questions on the clamp down of coaches and players with the establishment of an NBL review panel to eradicate unruly behaviour.
"The viewers want to believe they are watching a well-played, well-refereed game and if they don't believe that then maybe it's an impediment to them tuning in so that's really important from the sport's perspective of the growth of the game."
The difference, he feels, is if a player makes mistakes a loss is, perhaps, imminent and shoulders that burden. If a coach does, they return home to share a collective sense of dismay.
"If a referee makes a mistake, it doesn't hurt them but the team they have penalised go home and feel terrible so there's a difference because players and coaches' mistakes hurt them but referees' mistakes affect other people and that's the critical difference."
Consequently Coronel believes officials need to be held more accountable than the coaches and players who pay the price of a derailed campaign from accrued defeats owing to a lack of discipline.
"The referee's obviously not in a position to win or lose a game."
Nelson, he says, has also been working hard to lift refereeing to a professional standard with ongoing development and evaluation.
"He's very honest when he says coaches should establish a direct line of communication with him and, my experience so far, he's been very open to discussions about a number of things so, I guess, he's just reminding us to check with him to, hopefully, get improvements because they are new processes which take time."
