I would vote for somewhere in between if given the choice. I don't think Roddy will see last year's production level, but I do think his TDs will increase. If 2 or 3 pass interferences on likely TD throws don't happen and instead are TDs for Roddy, I doubt we are having this concern, even though his yardage might still be down. The drops are worrisome and are up compared to the past, but it's not like he hasn't had some drops in past years. To me, the best thing that has happened is getting Turner back as more of a focus, because it is in that type of offense where he has been most effective. You'd also think defenses would start to double Gonzalez more in the red zone until the Falcons show they can throw to someone else for TDs.
He's a disappointment to nearly all who drafted him so far, but he can salvage his season for his fantasy owners by coming up big in the fantasy playoffs. There's no way to know if that's going to happen, but far more unlikely events have occurred.
