Hmm... May I ask why?
While RG3 has been outperforming Cam here lately, I don't think that he will continue to do so going fwd. moreover RG3 has already suffered a cuncussion in his short career. He will be more susceptible to them going forward. RG3 is also smaller and IMO more fragile. Cam is a specimen. Once the League figures out Rg3 I expect him to struggle as well.
Cam is struggling due to the system that we're running this year...once they figure out to let Cam be Cam we're going to see an offeñse even better than it was last year.
Just my opinion, I have more to say but my iPad is being gay while I. Typing right now
