I gotta say, barber know has sealed his fait as a backup now. You dont fumble in sitaution like that, JJ will be back next week. Barber didnt run well at all today, he went down on first hits, and i mean he showed nothing, that he had last week.
I don't think Barber was anything more than a back-up anyway. I hope I'm wrong if he stays with the Cowboys, because he is nice to have when JJ isn't in there.
