Re: Sounds like Edelman's back
This is fantastic news. If true, that means he didn't resent the organization for not pegging him as Welker's heir apparent as some in the media had suggested. That and/or he didn't see the type of offers he was expecting in free agency (a lot players feel this same way). He can now be Amendola's direct back-up and a return specialist on special teams if he makes the roster.
From a role perspective the Patriots have effectively replaced Welker with Amendola, Lloyd with Sanders (if all goes as planned), Edelman's back to his old familiar spot as probably the top back up to those two. While bringing in competition for Branch's old role with JAGs like Jenkins/Jones, and camp fodder like Stallworth along with the expected WR purge of guys off the scrap heap.
Just one big, fast, physical true outside receiver should be all that's needed now.
