So who exactly is Englebert's boss? If it is the team owners, then the pressure is now on them. Yes of course they are mostly concerned with their profits and not raising salary and benefits in this new bargaining agreement enough to jeopardize that, but they can't be oblivious to the growing concerns.
The everyday fan already believes the players are getting screwed financially. The initial rookie scale contracts for the media stars that have driven an increase in attendance and TV ratings clearly puts fans on the player's side. Englebert's negative reaction to Unrivaled and of course Phee reeks of vindictive behavior by the face of a monopolistic entity that feels it can dictate terms.
The ref controversy is just one more piece of a variety of things shedding a very bad light on the commissioner and now the owners. I believe the majority of fans probably believe play has gotten too physical, and that is beyond the injury factor, it just isn't as good basketball to watch.
The owners may be relatively insensitive to outside criticism, but they can't ignore it completely. In the near future big name players, coaches, and media personnel may take a stand here, and if it is overwhelmingly against Englebert, with few supporters, they will have to make a change to save face IMO.
