The Facts: The Bills raised eyebrows in May when they orchestrated a swap with the Eagles for Brown. Seen initially as a dose of depth behind C.J. Spiller and Fred Jackson, Brown's name continues to surface as a player the team is excited about. Mike Rodak of ESPN.com wrote this week that Buffalo "would like Brown to develop into one of their lead backs" as the resilient Jackson begins his age-33 campaign.

Diehards Line: As NFL.com's Marc Sessler suggests, with Spiller and Jackson both entering contract years, planning for tomorrow makes plenty of sense. Brown is a decade younger than Jackson and comes to the team after piling up 4.6 yards per carry in limited action over 32 games for the Eagles. He plowed for 347 yards in back-to-back starts for Philly in 2012 but saw his snaps wither away last season under HC Chip Kelly. Brown remains a work in progress who already has more carries in the NFL (190) than he did in college (104), but his occasional flashes of brilliance suggest potential for a larger role in tandem with Spiller and Jackson for now. We'll see if that role evolves over time.
