Derek Carr is still top ten in QBR this season per ESPN

There are so many users here who want so badly for Carr to be the cause of the problems with the offense.

I don't understand how they can ignore the o-line play and say that injuries are not an issue on the line.

Carr isn't the problem with the offense, but he's also not perfect. Pointing out that he has issues and you would like a better QB isn't the same thing as saying he is the problem or not recognizing the injury issues.
