For those comparing this to the 2013 season:
2013 vs. 2016
Running backs
22 Stevan Ridley < Dion Lewis
34 Shane Vereen = James White
29 LeGarrette Blount = LeGarrette Blount
38 Brandon Bolden = Brandon Bolden
46 James Develin = James Develin
Wide receivers
11 Julian Edelman = Julian Edelman
80 Danny Amendola = Danny Amendola
85 Kenbrell Thompkins < Chris Hogan
10 Austin Collie < Malcolm Mitchell
18 Matthew Slater = Matthew Slater
Tight ends
47 Michael Hoomanawanui < Martellus Bennett
88 Matthew Mulligan = Matt Lengel
I see four upgrades and what I'll call a wash between Vereen/White and Mulligan/Lengel.
