We resigned him today.
Looks like it was just an emergency roster move for the one game only. I figured (incorrectly obviously) that we were letting him go so some desperate team could grab him as a starter. So the quarterback controversy that we have in our slow cooker now has three ingredients again instead of just two. Should taste really interesting by the end of the season.
I haven't seen very much coverage in the past weeks about how Chris is coming along learning the playbook / getting settled in.
