Stevie Johnson (No. 13)
Johnson's about as unorthodox as they come on the field, but he's emerged as one of the NFL's most creative and effective route-runners. He heads into the 2013 campaign after three straight 1,000-yard receiving seasons. About as nimble as they come, Johnson could thrive if he spends more time in the slot this season.
Robert Woods (No. 10)
To some, Woods was the most NFL-ready receiver in the 2013 draft class. He dealt with an ankle injury during his 2012 season at USC, which ultimately was a regression from the 111-catch, 1,292-yard, 15-touchdown masterpiece of 2011. He has 4.52 speed, is well-versed in operating within a pro-style offense and has soft hands. He is the early favorite to be Buffalo's No. 2 wideout.
T.J. Graham (No. 11)
Graham's rookie season would appropriately be labeled as a disappointment, as the former N.C. State track and football star had only 31 receptions for 322 yards and one touchdown. However, Ryan Fitzpatrick's ineffectiveness working the ball down the field certainly didn't help the speedster. With a major injection of young receiving talent around him, Graham will have to develop quickly.
Marquise Goodwin (No. 88)
Goodwin clocked a 4.27 in the 40-yard dash at the combine which made him the fastest-timed player in the 2013 draft class. He was an Olympic track star and efficient pass-catcher at University of Texas, although he didn't get the ball often. He should be used on jet sweeps, reverses and bubble screens, and there's a good chance he runs many "go" routes in 2013.
Da'Rick Rogers (No. 17)
Arguably the most physically talented receiver on Buffalo's roster, the 6'2'' 217-pound Rogers was a First-Team All-SEC performer before off-field issues ended his career at the University of Tennessee. He played at Division II Tennessee Tech in 2012 and was dominant, but his character issues dropped him from potentially Round 2 to the ranks of the undrafteds. If he matures and stays out of trouble, Rogers could contribute early in his NFL career. There's a little Brandon Marshall to his game.
Brad Smith (No. 16)
Smith hasn't been the do-everything dynamo Buffalo hoped he would be when they signed him prior to the 2011 season, but he's a serviceable special teams player, and there's no questioning his versatility. It'll be interesting to see if he can stand out among the slew of young receiving talent around him in training camp.
Brandon Kaufman (No. 14)
At 6'5'' and 214 pounds, Kaufman is a downfield and red-zone specialist who won't blow by many cornerbacks, but he doesn't have much problem outjumping them for the football. He's a longshot to make the 53-man roster. Then again, he could sneak in as the No. 6 receiver if his competitors falter.
DeMarco Sampson (No. 19)
Sampson is a 6'2'' 204-pound wideout who last played for the Arizona Cardinals in 2011. He has three career catches for 36 yards.
Kevin Elliott (No. 18)
Elliot is Florida A&M product who's 6'3'' and weighs 215 pounds. He caught 10 passes for 108 yards for the Jacksonville Jaguars in 2012.
Marcus Easley (No. 81)
The 6'2'' 217-pound Easley has dealt with a handful of unfortunate events since being drafted in the fourth round of the 2010 draft. First, doctors misdiagnosed an injury he suffered to his knee in his rookie season, and he was improperly placed on season-ending IR, though it wasn't needed. The next year, doctors discovered a career-threatening heart ailment that ended his season before it started. He underwhelmed in 2012 but showed promise on special teams.
Chris Hogan (No. 15)
Hogan spent the 2012 preseason with the Miami Dolphins but didn't make the final roster. Then, the Bills signed him to their practice squad. He was active for the final two games last year; however, he didn't record any statistics. He's 6'1'' and 215 pounds.
Dorin Dickerson (No. 82)
Dickerson is more of tight end than a traditional wideout but is currently listed as a wide receiver. He appeared in 11 games for the Bills in 2012 and caught nine passes for 117 yards.
