In the wake of the NFL draft and a host of undrafted signings Buffalobills.com takes a look at where the Bills roster was most effectively reloaded.
*Deepest position *Running back - LeSean McCoy, Karlos Williams, Mike Gillislee, James Wilder Jr., Jonathan Williams
Following the acquisition of Arkansas RB Jonathan Williams in the fifth-round of the 2016 NFL draft, Buffalo's number one ranked ground attack has more than their fair share of capable ball carriers.
Pro Bowl RB LeSean McCoy heads the group as the top all-purpose threat, followed by touchdown maker Karlos Williams and Mike Gillislee. James Wilder Jr. and the rookie Williams will bring more power and physicality to the Bills ground game.
*Most improved position *Linebacker - Jerry Hughes, Preston Brown, Reggie Ragland, Shaq Lawson, Manny Lawson, Eric Striker, Zach Brown, Randell Johnson, Lorenzo Alexander, Max Valles
With each of Buffalo's top two draft choices set to line up at the second level in the Bills front seven on defense it's hard to argue that the linebacker position has experienced the greatest influx of talent.
Shaq Lawson and Reggie Ragland along with athletic vet Zach Brown have provided Buffalo's previously thin linebacking corps with legitimate starting options and depth.
*Stiffest competition *Wide receiver - Sammy Watkins, Robert Woods, Marquise Goodwin, Greg Salas, Leonard Hankerson, Dezmin Lewis, Marcus Easley, Walt Powell, Jarrett Boykin, Greg Little, Kolby Listenbee, Gary Chambers, Davonte Allen
The comparable caliber of talent behind Sammy Watkins and Robert Woods is what makes this group so competitive. A collection of 11 receivers made up of vets, future free agents and a sixth-round draft choice will be battling for as little as three, and not more than four spots, on Buffalo's final roster throughout the offseason.
*Most new faces *Secondary - Ronald Darby, Stephon Gilmore, Corey Graham, Aaron Williams, Nickell Robey, Jonathan Meeks, Duke Williams, Jonathan Dowling, Sammy Seamster, Javier Arenas, Sterling Moore, Corey White, Colt Anderson, Robert Blanton, Kevon Seymour
The Bills defensive backfield might not see much change in their starting lineup, but the subpackages and special teams will have a host of new contributors. Buffalo added six new defensive backs to this year's roster.
At safety Robert Blanton and Colt Anderson were signed in free agency as were cornerbacks Javier Arenas, Sterling Moore and Corey White. Add in sixth-round pick Kevon Seymour and the new faces almost match the number of holdovers.**
*Most experienced position
Safety - Corey Graham, Aaron Williams, Duke Williams, Jonathan Meeks, Robert Blanton, Colt Anderson, Phillip Thomas*
The centerfielders in Buffalo's defensive backfield have the most experience among any position group at a little more than five and a half NFL seasons on average. Veteran free agent signees like Colt Anderson and Robert Blanton only add to the experience already at the position in starters Corey Graham (10th yr.) and Aaron Williams (6th yr.).
