Tough one. I think all three are good options this week, as they are all clearly their QBs #1 option in the passing game.
You have to be tempted on Brian Hartline after what he did last week, I know I am. I am starting him over Garcon this week.
Amendola you also have to like this week, especially when you consider he is facing the Cardinals, who just gave up 250 yards to Hartline last week.
I assume you mean the real Steve Smith and not the other one, in which case it is hard to bench him. I imagine you drafted him to be a stud, but he really hasn't been that yet.
As for picking between them, I am not sure what to advise you, because any one of them could have a big week. I am very tempted to go with Amendola tonight though, as you can bet the Rams will try to mimic what the Dolphins did to Arizona last week.
