I can't remember how Cam's preseason went, but I think it was unremarkable. I do remember his training camp being particularly awful - one analyst even went as far as to say "he doesn't belong on an NFL field!" Can't remember who it was, but they've still got their foot wedged firmly down their throat.
Let's put it to bed right now: RG3 will not have a Cam Newton-like rookie season, he just won't. Cam's rookie season was historical; that's waaaaay too high a benchmark to set for Bob. I will be happy with an injury-free season that shows progression and some nice numbers. 2500-3000 yards through the air, maybe another 500 on the ground, and 20-25 total TDs would be very nice.
