Wilks is a dead man walking, and we all know it. Highly unlikely he gets fired during the season - though another blowout like the Denver game just might do the trick - but at the end of the year, unless there is DRASTIC improvement, he's done. He's demonstrated that he can't put a staff together, can't manage personnel, can't make simple decisions like mandating that kickoffs not continue to be returned to the 15 yard line that could have been touchbacks, etc etc.
Next game should be interesting. The 49ers will be trying to avenge that loss to the Cards and will NOT want to lose twice to such a bad team. And for all their problems and injuries, the 49ers play balls-out every week - complete opposite of what this Cards team has shown thus far. Can Wilks re-gain the locker room simply by getting rid of McCoy? Maybe. But I'm very skeptical.
