IMO Robinson has been WAY underused and Van, when he came back had not been on the field for a very long time, wasn't anywhere near having his "game" going. Not saying Lance can't maybe make a statement, but really, for the most part it's hard for a high pick WR to make an impact , much less an undrafted WR as a rookie.
The season is shot, but I would hope that ARob and Jefferson can take up some of that non Kupp play, they are what we have going into next season as vets, Lance needs to get his feet wet for sure, but I don't expect him to out do either of the aforementioned 2 guys.
