I don't know why happened or didn't happen, but I have to question why anyone connected with Lias would advise any step he's taken thus far.
If he's having a health concern, be it mental or physical, or both, it should be brought up to the medical staff and the team.
If the team is unresponsive, that's where he has resources (and cover) with his agent and his union. For chrissakes, his father was a n NHL, he knows that.
If indeed there is a problem, have your reps handle the situation so you can control the message and let them do what they get paid to do. Not only would you have better odds of having the problem addressed, your team has a chance to make it obvious who the culprit is.
It's not that I don't believe Lias, because I don't know what's transpired, but there's so many unusual missteps and decisions along the way that there's no way to have at least some degree of skepticism. Even if, like most circumstances, there's some truth and wrong on both sides, I find it hard to believe that this is the advice he is receiving.
Because if it is, then his inner circle is not doing a very good job of guiding him, and if indeed they're telling him not to take the approach he's taking, then he's cutting off his nose despite his face.
