WR depth could still be a concern

I’ve said this in multiple threads. It’s all good now bc we haven’t had to rely on a 3rd guy yet. When those close games roll around, especially in the playoffs, someone will need to step up big. Plus, like you said in regards to an injury. This could derail our season.
Well, "derail our season" is a bit subjective. For a Super Bowl-or-bust fan, sure. But for others, this will be a great season barring injury to critical pieces - fun team to watch; solid character guys; likely playoff run.

That said, I do totally agree that we will not have a good feel for the ceiling for this team until we see this offense multiple scores behind and having to play 3-4 WR sets without max protection. And if that doesn't turn out well, we'll also get a good feel for this latest generation of post-2006 fans by whether/how quickly they turn on Carr and/or the O-line..
