My guess is Wilson. If they give up on him right now, he's gone.
I also don't think Wilson will make it to the end of the season if he keeps playing. His protection sucks and his upright style of running and trying to get out of trouble is going to get him knocked out very soon. Whomever they plug in there will have a tough time staying healthy.
I like the kid. I hope he does eventually end up in blue.
