I don't think he's going to be a big impact in the pass game, for the record. But we should feel him on the schemed up plays like the screens, jet sweeps, back side wheel routes, etc. He should be able to line up correctly which means getting on the field and just build on things from there.
What I'd really like to hear, though, is that he's showing progress on punt returns. I want that speed flipping the field for us just don't want to have a heart attack each time he catches it like Tavon did to us.
Oh and btw if he is showing extremely well in the pass game then that puts heat on Jefferson which is a good thing. Competition will drive improvement.
