Drop Davis for L. Robinson?

[djtw]

I need more WR so would it be smart to drop James Davis for Laurent Robinson or just wait this out and give it another week? Also would you try and trade for A. Gonzalez right now?

Not many available on the wire:
Robinson
Michael Clayton
Michael Jenkins
manningham
Cribbs
Troy Williamson
louis Murphy (Raiders)
Britt
