I think there's some truth in what he's saying. O-line is a mess and injured. Team offense is only alive because of Kupp. We could just as easily be 0-3. Stacked up against real teams (i.e. Bills) and our current play isn't going to cut it We're supposed to be one of the real teams and we have work cut out for us. Agreed about the style points. And a win is a win. There's plenty to get cleaned up.
I didn't know about Cam and practice, but his fumbles is a concern. Just like drops for TD's by receivers, bad throws, back negative plays, etc. Here's hoping McVay gets the team to tidy up these things
