I think one aspect of this team that is being overlooked is the fact that Adams & Stafford have had a full set of OTA's and all of training camp to work together. Last year they often seemed to be a bit off. Not always on the same page.
If Adams stays healthy, he could have an even bigger impact this year. Maybe not in shear numbers, and not just TDs, but more key 3rd down completions where last year they seemed miss on quite a few when needed.
Now, he probably will get fewer snaps in order to keep him fresh, but I think they will be much more consistent together this year, between the 20's, when last year it seemed more hit & miss, especially in the first half of the season.
