Any potential NFL star could be watching Cam and the social responses/negativity and learn a few things. It's pretty harsh, as expected. Most of it brought on himself - the celebrations in winning combined with walking off when losing, the theatrics of falling down on the sidelines, the whining to the ref when getting hit in the end zone, the pants, and on and on. Contrast that with Manning who didn't exactly throw lights out yet went out w/class given accolades from the fans everywhere and the media.
I think it's a pretty good case study to gauge how the fans and media will respond to things. I'm speaking primarily of Winston of course.
As I've said, there's a fine line between being arrogant and being confident. IMO, Winston is the latter but I hope he does well to distinguish between the two when he hits the big stage.
