Every drop, every catch, every little thing matters for Perriman ahead of the Sept. 1 53-man roster deadline. Free-agent signings Michael Crabtree, Willie Snead IV and John Brown, all top camp performers, are shoo-ins. Beyond that, the crystal ball gets foggy. Chris Moore likely is next in line. Behind him are Perriman and his apparent competition: sidelined slot receiver Tim White, free-agent signing DeVier Posey, draft picks Jordan Lasley and Jaleel Scott, and undrafted rookie Janarion Grant.
