I do not think that we were aware of the significance of his injury his freshman year. I think that he is still recovering from that and that is why he took the redshirt this year.
I think (hope) he has been dealing with a new injury. If he is still dealing with a 2 plus year old injury that is a very concerning sign.
I do think the chances of Joe being back at 157 are dropping. This year hasn't worked out as all had hoped so far.
