So the WR rotation or depth chart right now is:
Bourne
Parker
Ju Ju Smith
Douglas
Thornton
Boutte
Lots of questions marks in that group. Is Ju Ju going to bounce back? Hard to have much confidence in that. Parker is a year older but still potentially a solid vet WR. Douglas should be better. I still think Boutte could be a good receiver but he and Thornton may not even make the team.
Despite the questions, I don't feel like the Pats should invest big FA money in a receiver this off season. I would be happy with 2nd or 3rd round picks used for WR(s), and then maybe a second tier FA (and no, I don't know exactly who that might be). Hope for the best with Ju Ju, see how some of the younger receivers develop, and revisit next off season.
