Cut - out of the question - huge cap hit, and why? NFLPA could come after the team for cutting an injured player. Rams won't and don't roll like that. Can you imagine the headline hype with all the focus on concussions if a guy gets knocked out and then released by team.
As far as trade - for what? Who's going to take a chance on a guy with a concussion history and a huge cap number.
Hopefully he can shut it down for a few weeks and recover and if another one happens this season - the guy may retire at the end of the year and we would save the cap space next year. Personally, I don't think that will happen. I think he will come back and be ok.
