Who is one potential breakout player for each AFC East team in 2013?

Buffalo Bills: Last year Buffalo running back C.J. Spiller was one of the breakout players in the entire NFL. This season, Buffalo's breakout star most likely will be on the other side of the football. Bills starting cornerback Stephon Gilmore showed a lot of tools in his rookie season when he recorded 61 tackles, forced three fumbles and nabbed an interception. The Bills had the NFL's 10th-ranked pass defense and Gilmore took on the challenge as a rookie to guard the opponent’s best receiver each week. He is a fearless player who is already solid in a lot of areas. But Gilmore needs to work on making more big plays for the Bills this season and beyond in order to take the next step.

Miami Dolphins: The tailback who led the Dolphins in yards per carry last season was not Reggie Bush. It was actually second-year running back Lamar Miller, who averaged 4.9 yards per carry in 2012. Miller shined in limited opportunities during his rookie season. He displayed good vision and explosiveness, and appears to be a natural fit for Miami's West Coast offense under head coach Joe Philbin. Miller is the reason Miami had no issues letting Bush walk in free agency. Bush signed with the Detroit Lions after getting little interest from the Dolphins. Miller will get a lot more carries this season and pair with backup Daniel Thomas in Miami's backfield. Miller's weakness is pass protection, but he looked great last year carrying the football.

New England Patriots: The Patriots didn't necessarily need to draft a linebacker last year, but Dont'a Hightower was too good to pass up at the end of the first round. Hightower was considered an NFL-ready prospect and made an immediate impact with the Patriots. He recorded 60 tackles and four sacks with New England. Another year of experience should make Hightower even better in Year 2. Health permitting, Hightower should be a physical force in New England for years to come.

New York Jets: The Jets made several low-cost signings this offseason due to a tight salary cap. However, the free-agent signing that stands out for the Jets is running back Mike Goodson. He spent his career backing up quality tailbacks such as DeAngelo Williams, Jonathan Stewart and Darren McFadden with the Carolina Panthers and Oakland Raiders, respectively. Goodson averages 4.5 yards per carry in his career and is a projected starter for the first time in New York. Goodson has the quickness to fit in well with the Jets' change to a West Coast offense under Marty Mornhinweg. He'll need to keep up the same production with the increased workload.
