I think Doubs has the tools to be a top receiver in the league. I keep thinking about how he seems to compare to Donald Driver coming into the league, and remember where he ended up in the scheme of Packer history.
This doesn't mean he will be a splashy type receiver, but I think he could end up being the kind of target that can help make throwing the ball a lot easier, because he knows where to be, and when to be there, on broken plays.
This is just my opinion, but I think people might be pleasantly surprised by how good he really is.
