I heard on 610 this morning that they are giving Faggins and Earl more p.t. in practice. I guess if Robinson and Brown continue to struggle, they will make a move.
Personally I wouldn't mind Faggins starting at corner and Robinson learning the ropes as our nickel back (like Trufant did for Seattle his rookie year).
I also wouldn't mind seeing McCree get some reps at SS. He is a veteran and has experience at both safety positions. He has better coverage skills than Brown. Earl may be the future at SS but he is coming off of a tough injury AND is a rookie.
