Lets see how quickly Edelman's speed returns. Even Welker took almost a full season to come back to full speed from his late season ACL injury. So at least Edelman has more time to get in game shape.
JMatt is really just a slot guy, but the Pats use multiple guys over the middle with even Gronk in the slot at times.
On the outside I see Hogan (if he remains healthy) first and then Britt and/or Dorsett having opportunities.
Patriots will miss on trying to move Austin Carr to PS... they loved him and now Carr has a good chance for the slot role in NOS.
