One of the top competitions at Bills training camp will be for the No. 2 WR spot, with several candidates for the opening on the outside opposite Stevie Johnson. Donald Jones appears to be the leader entering training camp, with Marcus Easley being a wild card, as he has yet to play in an NFL game. Veteran Derek Hagan is another challenger. Third-round rookie T.J. Graham is not one of the front-runners, but he should factor into the receiver rotation as a stretch-the-field option. A track star in college, Graham gained 16.5 yards per catch at North Carolina State last season, and has drawn some comparisons to Johnson. “He has natural instincts when he catches a hitch or a slant. His abilities are similar to mine,” Johnson told PFW. “He can be a big threat.” Graham opened some eyes in OTAs and minicamp, and Johnson said QB Ryan Fitzpatrick also noticed the similarity between the two wideouts when watching film.
