Cameron's pace through the first four games was unsustainable, but there has to be at least concern going forward with Weeden back in the picture.
Beyond the fact that Hoyer seemed to make throws that Weeden hasn't (or can't), last night the first game where Weeden had both Cameron and Gordon to throw to (as Gordon was obviously suspended for the first two games). And while the targets were 6 to Gordon and 5 to Cameron, it didn't look like Weeden was looking Cameron's way a lot on his progressions.
Again, one game, but Cameron owners definitely got a taste of reality last night.
You make a point, but Cameron was a stud week 1 with Weeden. If you watched some of the replays, Cameron was getting some pretty heavy coverage for most of the game, obviously at the expense of Gordon. Teams can't focus on both Cameron and Gordon, so there will always be up and down games.
I just don't buy that last night's game was a "taste of reality", especially due to the Browns getting a punt return TD and defensive TD. The Browns won't be playing with the lead in most games. It was more of an anomaly, with the norm being somewhere between.
