In this respect, all I know about him is that it seems multiple teams have given up on him and he entered the assistance program last year. What's the deal here?
Keep in mind that nothing has been directly confirmed by the organizations or the player...
It's all but guaranteed that his player assistance stint was for drug rehab. The speculation comes after. Right around the time he
entered player assistance, he removed all references to the Red Wings from his social media, which later came into question when Detroit waived him.
Essentially, he went to player assistance, came back, Detroit put him in GR for conditioning and eventually waived him. Nobody claimed him, so he went to Grand Rapids. He stayed in Grand Rapids for awhile and Detroit was still competing for a wild-card spot at that point, so it was obvious to everybody that whatever the issue was, it was great enough that Detroit would rather bury a good scorer in the minors while competing for a spot than have him on the roster.
My
belief is that Detroit caught wind of a drug problem and told him he was going to rehab. Vrana wasn't open to it and Detroit essentially told him you're either going or we're terminating your contract. (This would spur Vrana dumping Detroit from all his social media) Vrana went to rehab, came back, and either copped an attitude with management about being sent to rehab, or quickly got back into drugs and Detroit decided they didn't want him around all their young influenceable players.
Reminder... This is only my speculation.
