Well I've been told that the D-linemen aren't playing so we can't draw conclusions from what we see. So have to go with what the coaches tell us. Still, if the D-linemen aren't trying, and Barclay is still whiffing, I think that's pretty good evidence ya gotta let him go. If I were in MM's shoes, I'd start Vujnovich at LT, tell him his whole career is on the line, that his legacy and his family's legacy, stability, and access to food for generations to come depends solely on his performance tonight and then see how he fares.
