According to Chris Brown of the Bills' official website, the deal is a reserve/future contract.
Little was signed with fellow wide receiver Jarrett Boykin and is the third receiver added to Buffalo's offseason roster in the past week. The Bills re-signed receiver Greg Salas in the first week of their offseason.
A second-round pick of the Cleveland Browns in 2011, Little saw his promising output from his rookie season decline greatly over the next three seasons.
After putting up 709 yards in 2011, Little went from 647 yards to 465 yards as drops plagued him. He was released by the Browns in May 2014 before being signed by the Bengals.
Little has a solid frame for a wide receiver at 6'2", 215 pounds and the physicality to outmuscle his defenders, especially in the air.
Other than Sammy Watkins, the Bills received next to nothing out of the wide receiver position last season. Watkins put up 1,047 yards in 13 games in 2015, while the team's next three leading receivers—Robert Woods, Chris Hogan and Percy Harvin, who appeared in just five games—combined for 1,220 yards.
They were quarterback Tyrod Taylor's supporting cast in a passing offense that ranked 28th in the NFL. Signing Little to a future deal shows that the team believes he could contribute in some way next season, but Buffalo's passing offense has a lot of work to do if it wants to improve on its subpar 2015 standing.
