I'm in the exact same situation and im going with ryan simply because he's playing at home and RG3 is playing @ TB. But just like I'm sure you already know at this point in the season, you really can't go wrong with either
And I disagree with the earlier poster. RG3 is taking a lot of hits this year so if I had to trade one I'd trade him. Plus, he plays in a division that has 3 good defenses
