I can't stand Alex. There is ZERO chemistry between him and JD, and it feels like he's forcing his delivery. Maybe with time he'll grow on me, but he seems every bit a subpar fill-in for me.
That said, to each his own!
My understanding is that he can be picked up by any team, though they would be bound to maintain his Rule 5 status and keep him on their 26 man roster. If he is not selected by anyone, he would go back to Detroit, which would cost them $50k.
