Wasting of Vincent Jackson

How do we not address WR with our first pick. A guy as talented as Vincent Jackson could get wasted if we dont have a true #2.  I realize that this draft is as deep as any can remember WR wise,  I think there are only a few that can be counted on to be effective right away and with Williams gone that face becomes more glaring.  I used to want to trade out of the pick, but I am leaning more and more towards Evans.  I do think he will be there.
