Gates is raw, and on the one play where he could have made a difference the DB easily got position on him so he was well out of bounds. WR is one of the hardest positions on the field to come in and produce, and I see nothing in Gates to say that he should be out there ahead of Hartline, Bess, and Marshall, who are all playing well (Marshall has had some so-so plays, but he still pulls in far too many catches and is too much of a matchup mightmare to pull off the field, not mentioning his ego). Hartline is a speed receiver and he's been plenty productive right now.
