I would probably go Rice. If it was a PPR, I might be tempted by Super Mario. He is gaining Smith's confidence and has been getting a lot of targets lately. If it's not a PPR that would be the only way to even consider Greene. But I still think he will go back to being less than mediocre as a fantasy back this week.
Need to know: PPR or not? What does the rest of your team look like, do you need the home run, or just to play it safe? If you think you need a hail mary to win this week, I'd go Rice. If you just want someone that can give you 6-8 points go Manningham. If you love Hawkeyes, go Greene.
