I don't think Ginn will be compeeting for the No.2 WR spot, at least not yet.
Hagan has improved greatly so far and I've heard nothing but praise for him.
Booker is a solid no.2 but he isn't getting any younger so I can see why he makes this argument.
IMO our WR depth chart will be
1)Chambers
2)Booker
3)Hagan
4)Ginn
5) Campbell or UDFA.
