Like the majority of our transfers out, Wes is gone because AU didn't want him anymore. He is no longer useful, so he is benched and/or asked to leave. That's fine, it's the only way to win games.
But then you can't expect someone like Hood to be loyal. AU wanted Hood to stay. He HAS progressed and knows where he stands, which is a good spot. He must be leaving for what he sees as a better opportunity, whether due to money, family, personal reasons, who knows.
I don't love any of it but I don't fault the players more than the coaching staff.
