Justin Rogers, Ron Brooks, Dominique Ellis, Crezdon Butler, T.J. Heath and Nickell Robey. All candidates to play inside against nimble slot receivers for the Bills in 2013.
Rogers and Brooks played extensively in 2012, but neither performed especially well. Robey is tremendously undersized, but he made his presence known during OTAs.
Yes, kicker. Rian Lindell no longer has a booming leg, and the Bills drafted kicker Dustin Hopkins in Round 6 of this year's draft to further assemble what's becoming Florida State North in Orchard Park, New York. The two will square off in a heart-pounding positional battle this August. The loser probably make won't the team.
Fullback/H-back/Hybrid Tight End
When it comes to traditional tight ends, Scott Chandler and Lee Smith will likely be the No. 1 and No. 2 in 2013. However, the trendy H-back position—a fullback/tight end hybrid—could be utilized by offensive coordinator Nate Hackett.
Dorin Dickerson has some NFL experience, but Chris Gragg was a multi-dimensional weapon at Arkansas before he fell victim to injury and ran a 4.50 at this year's combine.
Da'Norris Searcy will start as the No. 1 strong safety—although Mike Pettine's defense doesn't necessarily use that label—but he will pushed by rookie Duke Williams. With Jairus Byrd likely missing the beginning of camp, there should be a good deal of shuffling at safety for Buffalo.
