drop lavernus coles for defense?!

Need to pick up a new defense and would it be worth dropping lavernus coles out of all the wr for 49ers defense? I need a defense for week 4 and lavernus coles just doesnt look like what he used to be. He was supposed to be #3 but even he isnt producing more than any of my sleeper wrs. Pull the trigger and let this guy go?

Of that list I think I would drop Coles. Although your number 2, Berrian has also been a huge disappointment. (fellow owner )
