I think that would have been ideal. But I have dealt with many many situations like this in the workplace, from racial issues to sexual harassment to hostile work environments, you name it, and the key thing we tell people is to let someone know. Anyone. Anyway. Just get the issue in the open so it can be addressed.
I had one woman's mother come in and talk to me about a lead that was supposedly harassing her daughter. Her daughter was maybe 20 and felt very uncomfortable addressing this in any way, largely because we teach people when they are young to despise "tattle-tales" and that bleeds over into the workplace, making addressing these issues much harder.
I am glad EM brought the issue to light in a way he felt comfortable approaching it, it is serious and needs to be addressed.
I am also glad the Jazz has had some pretty swift responses and immediately reached out to the league to instigate an investigation. That is exactly how an organization like this should have responded.
I once had to start an investigation of a supervisor in one of my buildings because of a facebook post that someone brought to me from a previous employee who posted they quit because he kept calling her fat. Key thing is that this gets addressed, that EM feels heard and acknowledged, and that DL is treated as innocent until proven guilty. By the comments on a lot of the tweets there are already people basically calling for his head, which to me is the worst thing about a public outing like this. IF he is shown to have done this, they need to fire him, especially after his public denial. IF it is shown to be a misunderstanding or at worst a he-said/she-said I hope EM can move forward, and I hope DL can salvage his reputation somewhat, although I imagine that damage will take a long time to undo.
No matter what I hope the organization takes this as an opportunity to check the pulse of their employees on issues like this, and educate everyone. In short, to get better as a group.
