They doubled Megatron right from the start. Dunbar had Smith but he too drifted to the endzone worried about CJ. That's the thing about Stafford. How good is he vs how good does Megatron make him look?
I was actually thinking about this earlier today, and I suppose that the conclusion I came to is that ultimately they work as a combination. It goes without saying that Stafford probably wouldn't be as successful without Calvin, as he can open holes for other receivers (see the picture a page ago), but at the same time I think that Matt does have a lot of talent. CJ has the ability to jump up and catch a ball in triple coverage (see also: Lions vs. Cowboys 2011), but not every quarterback can make the sort of throw that allows for that, and there is more to Stafford and the offense than just the "throw jump-balls to Megatron" approach.
After all, if all it took was a fantastic receiver and a mediocre quarterback, then why haven't the likes of Leinart, Kolb, and Skelton found any success with a "throw jump balls to Larry Fitzgerald" approach? And why has Calvin Johnson only made that step up to being recognized as one of the league's greatest weapons after Stafford developed and stayed healthy last season? He didn't have anything close to that level of success with Kitna or Culpepper or even Shaun Hill. Calvin makes Matt better, and vice-versa. And when the two of them click, the rest of the offense opens up immensely.
