Because unless the guy has been kidnapped and is being held for ransom, you would not think he would be doing so much to torpedo any chance he has of being offered the chance to get paid in the majors in the future. It may an assumption, but it’s a pretty decent one. There just aren’t that many possible circumstances that would preclude him at least communicating. And the league has established diversion channels for things like substance abuse. So I’m guessing this does have to be either something really weird, which is what makes it interesting (possibly), or he just doesn’t want to play for Det., which would be irritating.
And might also reflect back on FO incompetence for not having done adequate homework.
