It's pretty self-explanatory.
You believed it didn't make any sense, at all, that it could possibly be sexual harassment as he'd be fired, but now you're entertaining the possibility it could be framed as "sexual harassment". It speaks to the entanglement of mental gymnastics you've got yourself into in this thread. I made sense of the situation as it occurring after the consensual relationship (as everyone did in the thread), as it typically does in these instances; that doesn't take away from the notion of it being sexual harassment, regardless, if it occurred before or after.
You're the one who switched up his shyt.
Furthermore, it'd be remiss to think just because it occurred before that it doesn't have the same gravity (as after), as women in lower-ranking positions can easily fall victim into being preyed upon, putting themselves in a position where they enter a "consensual relationship" out of fear of losing their jobs or their reputations being marred. Now, that's not to say that's what happened here, but this is the reason why workplace relationships, particularly when it involves a subordinate are not only frowned upon but forbidden.
Even if Udoka is relatively innocent in all this (in a moral sense), then the punishment of a one-year suspension and his place in the NBA forever tainted, is justified, if only for the fact it'll scare coaches or any high-ranking personnel from going down the same path (where it leads to more devastating consequences).
