Yes indeed, you are right about that because earlier in the season Cam wouldn't check down to save his life. I can remember games where the rb's were open and he would not even look their way and throw a pick. Most of the times the rbs would be in a position to pick up first down yards and larger chunks.
He apparently had done quite a bit of work with Shula recognizing defenses and using the checkdowns and quick hitters to the point that his recognition and ability to audibelize has improved immensely. So they have opened things up ran a more NFL style offense with more power running options and we have an explosive offense the past few weeks.
So I agree with those statements.
Also, I think Cam was trying to relive the team being the most explosive offense from last year which could have clouded his judgment to make something from nothing, especially when you have a Smitty in your ear saying, "one man i'm open, 2 man i got a chance, 3 throw it to me and see what happens".
