I think you should go after RG3, but agree that you should wait a few weeks. He is overvalued right now, in response to his performance. You actually hope he has a terrible week soon, then you can offer less for him.
Also, I'd hang on to Ridley, the Hernandez injury will probably force the Patriots to run a little bit more consistently now.
If you get a chance, I'd love some insight on this: viewtopic.php?f=18&t=521264
